Yeah, sure. Ostalgie is second best, and Mao was lukewarm. Problem with Ostalgie for me was that its too on-rails, where you basically have to do a checklist if you want the perfect run. Meanwhile CitK was great because even in the ass that is the 1991 starting date you could turn it around. Maos Legacy was bad, because it had a chance to be CitK 2, because you're playing freakin' China, but instead you are even less influential than Stasi GDR in Ostalgie.
Also about Collapse and things it fucks up: enemies. In all of the last three, even Mao, you had specific rivals : Deng, Khruschev, NATO, Yeltsin, party wings, your own people etc. Here there is nothing. I guess different parties, their paramilitary wings, sepratists, NATO, CIS and factions are supposed to replace them, but in no way they feel like enemies. They are anoyances at best (factions which you just bribe) and don't even seem to do anything in most cases.
Speaking of opposing parties, what the hell is up with their AI and the laws they make? Do they just throw shit at the wall? This whole thing feels like an awful alpha build.
