solar and battery factory?
 - rare earths?
 - lithium
 - plastic products
 - steel?
 -> renewable energy products?

plastics factory
 - refined petroleum -> plastic products

chemical plant -> refinery
 - minerals -> chemicals
 - oil -> refined petroleum


0.7 alpha 8:

fix town hall texts, using text stack?
roadtype crossing groundtiles are wrong
bring roadtypes up to parity with rattroads

need to enable slower production mechanics on chemical plant to match other production industries
also enable custom production for water pumps and farms to match all other industries

remove current electricity mechanic, switch to solar panels?

=========================
v2 / 0.7 Release:

24 24 24  72
3  3  3   9


16 / 8 = 2

alpha 5 industry ideas:

town hall industry, includes info on what to do for town growth (done)
robot factory? only in advanced economies? if so then what to do about no wastelanders?
substations on edge of map for post town-growth electricity? maybe only if not doing robot factory? (done, may change for other economies)
should (some) industries require electricity? if so does it enable function or do a boost?
should power plant supply info to town register so buildings/industries there don't need power lines? can't do this exclusively because it needs too many power plants to be reasonable

remember to fix (mention) destroyed house protection callback (pointing to wrong switch) in alpha 4 (done)
need higher capacity ships, for early game
need to split electricity carrier into two: one 1/2 current capacity and the other double (done)

alpha 2:

landscape:
 - airports (done)
 - roads (parameter combos, and add non-destroyed non-roadtype variant) (done)
 - industries (decouple from ground sprites) (done)
 - houses (self sustained)
 - railtype tunnel overlays (done)
 - non-roadtype road tunnels (done)
 - hq (done)

change train sprites to 6/8 length (done)
change secondary industry production to use 1/8 consumption
make renewed houses not disappear when wastelanders are being transported from a town (done)
maglev too long??
fix wastelanders, again (done)

alpha 1:

severe: offshore colony can spawn partially on shore. possibly related to other industries being able to spawn on slopes (maybe fixed?)
rework railtypes and rail vehicles
add jet train (and all other vehicles)
relabel SCRP -> STEL and _OIL -> OIL_ (done)
change trading post into scrap yard (done, except graphics)
make shack houses accept irradiated food (done)
extend building materials chain (done)
draw new cargo icons (done, for now)
add new steel mill code (done)
add sand pit industry (done)
change power plant behavior (done)
add electricity "vehicles" (done)
remove steel(scmt) as valid cargo for hoppers, add sand and coal (done for trains)

fast ferries are a bit too expensive - 30 tile route fully loaded loses about 20,000 per year
 - all ships? (done)
airplanes seem a bit too cheap
helicopters may be a bit too expensive
early trains may be a bit underpowered (done)
rvs also a bit too expensive (done)
change prefab plant graphics to look more like temperate factory
add cargo production callback to houses to prevent mail generation at 3 or less buildings (done)
also to prevent passenger production on destroyed and shack buildings (done)
add protection callback to self-sustained houses when pax_transported = 0, and no other cargos delivered (done)
extend cargo check radius to 14 tiles (done)
improve one way and blocked road sprites (done)

============================
0.5 Release:

look at steel mill sprites from dormant to active...it looks strange somehow (done/fixed)
look at fixing passenger numbers displayed on offshore colonies (maybe add consumer to produce block?) (done)
    ^^update: critical bug - causes vehicles to not make money on delivery once at 65,535 waiting!
fix industries being able to be built on slopes
fix refittability of aircraft/check other vehicles (pax is no longer express cargo) (done)
make note about asphalt roads coming out 1 day after game start

fix intercontinental airport green grass
fix level crossings (done)
add some interesting eyecandy for remaining rough land sprites?
make proper roadtypes (done)
fix scrap metal color being invisible in graphs (done)

make flame stack on chemical plant stop flaming when no recent service (done)

==ADD GRAPHICS==
 - vehicles / rvs first
 - houses!!
 - industries??
 - atlas mfp STILL in progress
 - Food Lab
 - finish maglev track
 - tunnel sprites for tracktypes??
 - more landscape variety??

fix passenger/wastelander weight (should be ~150-180 lbs or .075-.09 ton) (done)
(optional) remove CC_EXPRESS from pax/wastelanders cargos (make sure doesn't break savegames!) (done)
create vehicle rosters for monorail and maglev

finish vehicle spreadsheets and post to website

==============================================
==============================================
==============================================

add ccnw's industry production changes (done)
Finish drawing water pump (add big pipes to side, and shading/details)
Begin/finish food lab/other industries sprites

add separate trailer spritesheets for each articulated rv (done)

Now (Current Fixes):

give all vehicles explicit ids, each spaced 10 apart (done)

town growth tweaks? 
 - keep towns from shrinking when only one cargo is delivered (done)
 - try to make it so towns don't build shacks or renewed buildings once self-sustained ones start appearing (already done)
   - also prevent lower class buildings from replacing better ones (done)
 - possibly make self-sustained buildings appear later (higher amount of buildings? or somehow based on town size?) (done)
 - add town shrinkage checks to all buildings, not just destroyed (done)

 - maybe add check to protection callback to ensure there are other similar buildings nearby before destruction, to prevent town spread. (done, but implemented in failsafe instead of preventing destruction. should investigate further)

road vehicle stat tweaks (ongoing)
 - space out intro dates/make vehicle life match model life (done)
 - increase base cost multipliers and change all vehicles' cost factors to suit (done)
 - exaggerate vehicle stats to give different vehicles more purpose (done)
 - maybe make low class vehicles into feeder vehicles (done)
 - increase hopper vehicle stats (capacity, mostly) (done)

make gravel (more) profitable? (maybe wait till trains are implemented, see if they make profit first)

make articulated vehicle purchase costs more appropriate by modifying refit costs to reflect price differences (done)
add scrap cargo to road vehicles (hoppers/flatbeds) (done)
add appropriate costs to all rail wagons (done)
add appropriate costs to ships (done)
add refit costs to all vehicles (done)

adjust small airport graphics for wasteland

adjust model life dates on all vehicles so there is 1-2 yr crossover (done)

give credit to supercheese in readme file! (done)

fix purchase costs of RVs (done)


------------------------
Next Big Release (0.2):

new industries/cargoes
trains??? <= (trains are next priority after rvs)
aircraft??? (new industry chain requires either aircraft or ships in order to be useful)
tracktypes?? (should be done if trains are to be implemented)

-------------------------
Later (or whenever):

add visible stockpiles for food lab
