Thanks a lof for the reply and info. I dont see as a bad idea release core game for free as demo and only sell modules... the range of prices is high BUT if in the 40$ enter things like the World At War volumen compendium system is not bad at all (i think in tematic packs like Heroes of the Blitkrieg+In defeat defiance) even you can use a "free" pack sytem to sell with discounts... i think in buy 2 packs with 20% discount or buy 3 with 30% discount. I like the non presence of DRM usually this provide more problems than advantages. Again thanks for the info, HoP and WaT have some followers in certain circles hehehe. PD: you plan add some kind of "automatic" system to reduce the human presence in turn resolution??? i refer that now to play Human VS human you need play on-line but if players can set some automatic reactions to units maybe with this some kind of PBEM could be posible... i read very good things about the serie but here people find hard play VS humans thanks to the problem in time+space requirements.
