Gosh, you know what I am worried about? That they take everything away that made the game great, and turn it into a more actiony game like ME2.
Ugh, I hope not @ DAO going to get more action-esque. I like that's PC-style, built for KB/mouse - very stragetic and BG2-like. DAO is the best of that kind of "full-control RPG-strategy" game since BG2, probably. Sure, NWN2: OC, NWN2: Mask expansion, and Drakensang: The Dark Eye were all ranging from good to great - but hell, they ain't as great BG2 and they ain't DAO. BG2 and DAO are masterpieces from Bioware.
Mass Effect was originally on X360 and is more of a direct-style control kind of thing (since it runs on a modified UE3) - so inherently, it's going to feel more like an action game by nature (in the combat), despite it having plenty of RPG elements (leveling-up your character; decision-making impacts the game's main quest, side quest, NPC's, and gameworld; loot-swapping; socketed loot that can be improved; etc etc). I just think ME PC, DemiUrge and Bioware got smart and decided, "How can we make this feel more at home on the PC?" And well - they easily figured that one out.
DAO PC, even though you can use direct-style control play (WSAD for movement or cursors - similar to what's in KOTOR), you can use click-and-point. Decent-sized party (four) and that extra overhead isometric-view - that speaks of strategy to me - that just seems more fitting for a KB/mouse. In fact, if Bioware was smart and didn't want to "dumb down" the console version, they'd ALSO just allow for additional KB/mouse support on the X360 for this game.
Oh, I haven't checked - but since this game is also on the 360, does DAO PC version support 360 controller?
On another note, my nephew has DAO for the X360 and freakin' loves it.
