Now, after the xth iteration, and considering how easy it is to figure that this utopia is actually a dystopia (yeah, let´s have 30 battles in the east, each day! - it sure wont get repitive very quickly... - and the AI will of course be a challange in those battles, too, right - i mean like in CA-games, it is...), i´d hardly call that an idea, though. I dont think it´s asked to much, for the idea-givers to at least have spent minimum thought on what they are suggesting. If the ´idea´ would come up only like once a year, i´d just ignore it - but it crops up way too often. In fact, it´s becoming a threat to the franchise, i feel. If it will be the most requested feature for HoI4, i can see PI actually trying (and failing, hard - except maybe commercially, which will be the temptation for them to try it in the first place). You know, how classical cRPG died? Just like that.
EDIT: Aside from PI´s ressources, such a feature would ruin the game, anyways. If the suggestion was at least: ´I´d like a spin-off, in which you command a single corps (of your choice) embedded in a bigger AI-run campaign, with TW-like battles... ("HoI - tactical episodes", or some such)´ - now, that´s something different - still wrong company´s forum, maybe, but at least plausible as a game-idea, imho.
