I don't think many people would buy DLCs with e.g. 5 buildings (especially "recycled" CiM ones). I'd rather buy (for a reasonable price, though, I wouldn't be willing to pay €20 for that, €10 woul feel appropriate) a big pack with a whole big European style buildings set. You guys don't even need to produce much new stuff: you already have the textures and whatnot from CiM 1, and I'm sure lots of people would buy that, only to be able to build European cities (for me personally the American ones are completely soulless). Also, give us railways and all the railway props and buildings like stations, cities are empty without them!
