DA2 yes, I think EA put too much pressure on BioWare to churn it out as fast as possible. Less than 18 months after Origins? We should have had another expansion to join awakenings before a sequel at the very least. Origins had an awful lot of life, but like Valve with L4D, it was sequeled in very short order. I have no idea what kind of community formed around it, as they did around NWN and that's the tragedy. BioWare used to make epic games that span generations (as Bethesda still do), now they make throwaway console titles.
The game was a lite RPG with none of the good things about Origins and lots of new bad things. No equipment for companions? No ability to choose different race? I won't deny that it can work being pushed into a single role (eg. Shepard, Geralt of Rivia, Mike Thorton, etc) but Origins was great because we could make our own characters. The copy/paste of every cave map, mansion map, courtyard map was jarring, showed poor production values and broke immersion. I'm torn over how it's been "MMOd" up...on one hand, the action was satisfying, on the other hand it didn't have the tactical depth of its predecessors.
ME2 was brilliant. Hate the DLC shiz but the games industry has gone down that road now and they're never comin' back. I HATED the global cooldown crap and the fact it became a cover based shooter. But the action, particularly as a vanguard was just enough fun, with good RP opportunities and a great supporting cast that you can forgive the shortcomings. Also, Biotic Charge.
Anyway, it's not entirely BioWare or EAs fault. The consolisation of the games industry is the biggest culprit. If I could have a wish, it would be for an indie BioWare to make one last PC RPG, but that will never be. In fact, a current gen remake of BG2, with voice acting...I wouldn't get any sleep for a week.
