For those who just want my opinion the tl;dr version is I think Bioware is doing just fine
I've been hesitant to post on this topic but hell I just will. I figure that some of the things that I like about Bioware and their games are going to be some of the things people hate (and vice versa) Going to throw a little disclaimer out before I comment that I haven't played any of Bioware's "fantasy" RPGs (Dragon Age etc) So if there is any declining quality or the such (from reading this topic it seems like many people feel that way) I haven't taken that into consideration
My first Bioware game was Mass Effect 2, I was looking for a Battlefront-esque shooter with a deep, engaging, story line in a sci-fi world that I knew NOTHING about. Describing that to a friend, he walked over to his game rack, pulled out Mass Effect 2 and said "Your wish, fulfilled." As with almost any series, I knew starting in the middle had the potential to be problematic but my friend insisted it wouldn't be that bad and in his opinion ME2 fit my style more then ME1 would. After playing through the opening (I was a little lost I'll admit) and I got to the main story arc I found myself having a lot of fun, Leveling up was easy and fun (something that turns me off RPGs in general) and with each level and ability it felt like I was playing more to my style then traditional shooters which pretty much give everyone the same shit, throw them in an arena, and watch them pummel each other. The one thing that I REALLY liked was the Resource Mining, something that I hadn't seen since my RTS days and it gave me a real since of "hey we aren't just going to hand everything to do you, you gotta work for it" I felt the story to be deep and engaging, I felt my self sympathizing with the characters and their troubles and though I lost a few people in the final mission I didn't feel at all slighted in the story in anyway by the ending.
After I finished ME2, I not only went and bought it and all the DLC, I bought ME1 as well. ME1 however, did not give me the same enjoyment as the sequel. The story was very well done, I liked the more missions both main and side quests. But the sheer amount of stuff being thrown at me through completing quests, finding crate, locked crates, lockers, etc and having to go to the Quartermaster after every mission and unload all the crap that I didn't use for me or the 2 people I was had with me just turned me off for some reason. The combat didn't seem to have the same type of flow to it, Once I leveled up and got the best equipment, the game didn't feel like much of a challenge to me and the vehicle sections...I'll just say I would like the planet exploring with the HammerHead more then the MAKO...
I've been following ME3's development extensively and it SOUNDS like they are trying to mix them to together in just the right way that it will appeal to the people who liked ME2 but still appease the fans who thought ME1's style was the better style. I think that having the different modes for different play styles (action, story, and the traditional RPG) is a very good step. I'm a little bummed that the Resource Mining is going away but it seems like I'm in the minority on the enjoyment of that. I'm sure Bioware will do just fine in the new style they use for that. The multiplayer I'm not going to judge just yet because I was heavily critical of Assassin's Creed and the inclusion of multiplayer only to be smacked in the mouth when it was actually good and I found myself enjoying it.
I think people's criticism of Bioware might be premature or unfounded, but that's just me. I think it's too early to judge where Bioware being under EA. They've released a couple games since merging with EA, some good, some maybe not so good. I want to give them more time before I write them off completely
