I played long before steam has kept records. After counltess hrs of play, I can confidently say this is an awesome concept with poor and unfinished programming. There were many great modders and community support for this game, I dont know if they are still out there. I do remember there was an unofficial patch that made a lot of corrections, helped get rid of bugs and eventually made the game playable. I think the name of the mod was "Germany Hannebu"
I believe the fault is in steam here, they should have had it overhauled before releasing it, just like numerous titles it had released this way (steam edition games)
So as a summary, dont buy it from Steam but if you can find it elsewhere grab it.
