Seems that this forum died a bit. What happened? Everybody gave up?!
I'm bored at the moment, so I'll try to speculate a bit. Assuming that all known game breaking bugs will be squashed in update 3, that leaves us with some game polishing for update 4. What to do in update 4??
* Teach AI how to use CVs and airplanes properly
*Teach AI how to build structures (maybe I'm wrong but seems to me that my neighbouring countries do not build anything for decades). Maybe some script for AI to try to build buildings for providing deficient resources. If AI do not have sufficient coal production then it builds coal mines. If it lacks power it builds powerplants.
*Unit training - option to train units. possibility to create core of elite, well trained units like in RL. Training would require time, money (based on maintenance, so training fighter squadron is much more expensive than training special forces or artillery), fuel and supplies. So, basically ,training will be very costly. Units can be only trained up to 50 percent of full possible experience (bar).
*Veteran and rookie units - trained but untried unit is not reliable. When under fire, unit can show that training was unsatisfactory or much better than expected. So, after first combat contact unit experience level is randomly modified in +/- 50% range of it's current experience level.
* Unit perks - when training unit, we can set the goals of training (urban fighting, FLAK trap, anti submarine combat, fouling air strikes, defensive combat, anti tank experts, expert scouts, tank busting, wild weasels, supply wizzard and so on). So, urban fighting perk would give unit +30% in close combat/defence and fouling air strike will give ground units +50% air defence (simulating equipment dispersion and camouflage). Every unit can have up to 2 perks- one which can be trained (training can fail) and one which can be awarded in combat. So after succesfull combat in the city, tank unit can get "urban combat" perk (sometimes, not very likely).
*Speed up gaining combat experience. Experience in combat should be accumulated much faster. I had wars which lasted for 10 years and units which constantly fought for years and they hardly gained 50% experience. I had submarines with 100+ kills which had much less than 50% experience (bar). Seems bit too slow to me....
* Renaming units. Not really important. Don't know if this is fixed since I never tried to rename any unit since I failed renaming for the first time.
Disclaimer: I'm really bored and hope that this will bring this forum back from the dead. I also hope to hear some more fresh ideas for improving this great game. I also don't expect any comments from authorities
They shoul'd just increase the cost of training. And by that way, getting elite units = very costly.
