What's Your Favorite Bioware Game?

So close, may just depend on my mood. But...
1) Mass Effect (extra points for the original, and it has the best, most complete, story of the three)
2) KOTOR (similar reasons, for a different franchise). This kicked off my love affair for BW games.
3) DA:O (because ... well ... notice a trend?)
4) Mass Effect 3 (yes, I prefer 3 to 2, even with the LOUSY ending. But TBH, ME2's Giant Human Reaper was laughable, so not a great selling point). So many complain about lack of closure. I take the entire game to be a sequential series of closures.
5) Mass Effect 2 (mostly for the loyalty mission stories)

For reference, I aslo played KOTOR2, SWTOR, DA2, Anthem. I have most of the few others but haven't worked up the motivation to give them a full play.

Yes!  I feel the same way I look at the Trilogy as one big game.  The Mass Effect Trilogy is my favorite series BioWare has done.  Dragon Age: Origins and Dragon Age 2 are close behind.  As well as the game that got me into Star Wars the original KOTOR.

My favorites are the Baldurs Gate series.

That's easy...

Dragon Age series, followed by Mass Effect series, and SW:TOR
and I'm also including Neverwinter Nights 2 despite it having been made by Obsidian

Since Kotor 2 was an Obsidian game, I enjoyed ME3 for the multiplayer and its Geth arc with Legion. Still beats anything Co-op related made today.

Sad not to see any love for KotOR so it gets my vote. Mass Effect 1 and Dragon Age 2 are very close contenders as well.

ME1 and DAO are my favorite games from Bioware. I voted for ME1 because i maybe like it little bit more

You can tell this poll is not representative because ME2 isn't far ahead in the lead—I voted DA:O myself, incidentally.

DAO but Kotor is a close 2nd. It was my favorite game prior to playing DAO. After that it gets more difficult but maybe ME2.

Yeah. ME2 is the game I most frequently see cited as Bioware's best outside these forums, both by the average gamer and gaming publications. It makes sense, too: Mass Effect is undoubtedly Bioware's most popular franchise—Baldur's Gate, Neverwinter Nights, and KotOR are too old and out of their hands; no one remembers Jade Empire; and Dragon Age is too dorky and relatively old school for the AAA scene—, and ME2 specifically is more of an action game than ME1 while lacking the controversy around ME3 and ME:A.

All three of the original ME games have their strengths and weaknesses. Personally, I'd probably consider ME1 the best game in the trilogy, as it is a better RPG than the sequels, has a stronger plot, and a more thoughtful tone. And ME3 is the most inconsistent of the trio, swinging wildly between some of the finest moments in the franchise and utter dumbassery. I actually think it handles companions the best, and that ME2 is overrated in that regard. The latter's virtue is in being the most stylish. I believe Blade Runner was an influence, in aesthetics if not themes.

So yeah, I'd agree with ME1 > ME3 > ME2. But like I said, DA:O is actually my favorite Bioware game. Too bad the sequels are among their weakest.
