Because games shouldn't evolve at all and we should keep playing BG over and over again. Because it was the pinnacle of gameplay and the trash AD&D ruleset they used didn't svck at all for video games. And the Highlander storyline was also the pinnacle of originality.
I loved BG back in the day but I can tell you that I've played Mass Effect 1&2 far more than BG1,2 and ToB by now, despite the ME games coming out almost a decade later. Not every gamer is stuck in the past/comfort zone, some actually like advancements made in modern games.
And I love it how you try to blame it on EA, when actually Bioware's head honchos have the final say on every RPG that is in development in one of EA's studios.
Maybe someone at Bioware simply realized how ridiculous your silent PC looked whenever he performed something dramatic in a cutscene/dialogue.
Problem is, Dragon Age was very long in development, several other Bioware games were released between the start and finish of its development and it shows. Dragon Age is a fantastic game no doubt, but there are many parts where its old origins(no pun intended) show and not in a good way.
Where did I say that BG was the pinnacle of gameplay? I did say that DA:O was intentionally going back to the "traditional" type of game. I will admit, that I tend to believe that EA has a great deal of influence over what EABioware is now doing. Sorry, but when the Jade Empire, a Bioware xbox exclusive released in 2005, took 2 years to be ported to pc; released in 2007, and ME, which was a Bioware 360 exclusive released in 2007, was announced as coming to pc shortly after EA bought out Bioware and released in 2008, I think EA has something to do with it. My personal opinion only; your mileage may vary.
The whole hype thing for DA:O was the "traditional successor to BG". I think, again, my opinion only, one of the reasons it sold as well as it did, is that I'm not the only one who followed the development of the "unnamed Bioware project" on their forums [due to WotC issues, they weren't going to use D&D rules and made up their own, iirc], as it turned into "Dragon Age" then morphed into Dragon Age: Origins, and wanted to play that game. The story having been done before doesn't bother me; some people believe that there are only seven basic plots; every story is a variation/mix and match of the basics. I'm waiting to see if, in ME3, Shepard has to use her/his connections, friendships, and alliances to build an army to face the darkspa....um...face the reapers and save the galaxy.
I play ME and ME2. I even enjoy them for what they are. At least there was a story [human hero perseveres despite ridicule and TRIUMPHS; not quite Highlander, but still been done before] in ME. ME2 has a lot of gunfire and explosions with a hero turned traitor but not really its for the greater good story. In between the sweeping cinematics there are opportunities for semi-interactive clicking, with good/neutral/jerk dialogue. If they emphasize the cinematics any more they should just leave out the semi-interactive parts and release the movie, imo. Don't spoil the sweeping cinematic thing with irrelevant player added interactions. Advancements? Some, I guess. Worth it for more than the "oooh, new and shiny" factor? Maybe. I do like the sniper rifles. Other than that, though, I had no problems leaving ME2 and going to DA:O, DA:A, Oblivion and Fallout 3 for that matter. I guess the cinematics aren't enough to keep my interest.
For the combat shouts/give you a ladder interjections; I'm careful when picking the voice for my character. And I think they've reused the voice sets from their other games; I think I recall hearing a few of them from my female Revan. I can ignore those more easily than hearing my pc say something that is completely different from what I wanted them to say. Oh well. It will be interesting to see what it looks like when its finished.
