I never got into the first game, I downloaded a pirated version from my friend but the textures were broken so it looked like an n64 game.
All I heard about the second game was Tali and all the f-ing romances. Thats all people blabbed on and on and on and on about for years was their f-ing kawaii desu alien romances. Could you get into a game if thats all YOU ever heard about it? It was nauseating. That and all the hype made me not really interested in it. Luckily my friend got 2 free copies of the game when he went to comicon, so I got one. I played 75% of it using mainly Mordin because he is the only funny one of the group. Its an alright third person shooter with dialogue options that dont really matter. I mean, they dont really matter. You can humor yourself that each action you make affects individual story elements that combine to create the most elaborate game ever created, but thats just being silly.
The third game I don't see a point in buying or playing. Why do I need to "finish my sherpards story" or some shit again? The second game had good enough backstory so I didnt need to play the first, and a good enough ending of YOU SAVE ALL THE HUMANS that I don't see a need in playing a sequal. Especially when the sequel is 60 dollars with content cut for dlc and a supposedly shitty ending. Maybe when its like, a complete edition for 20 bucks in the near future, but by then Bioware will have probably made some new Mass Effect shooter.
I'm 19 btw if you're curious about my age, and I have never gone onto bioware forums or really any forums to rant about how "bad" or "good" any of the games are because thats petty and childish. I am not trying to be a negative nancy, but the games to me just seem alright. Not too amazing, kinda bland in a lot of places, and some terrible facial animations.
