Just finishing off the game... all that multiplayer just to see a 1 second clip of Shepard maybe being alive was rather pointless. I don't get why BioWare can't do a satisfying epilogue/denoument to the games.
As for the series as a whole - the problem is that they had no idea what they were going to do, so they went to back to the well that was all so familiar - The Matrix. I mean, Babylon 5 had pretty much the same story in its first three seasons and even though it ended with what amounted to a yelling match, it still came off better than this weird half-ending/cop-out measure.
Perhaps it's unrealistic, but what they should have done was have each game be a self contained "movie" or "episode" with a complete arc. There's no reason this storyline needed 100+ hours to tell (the equivalent of 5 TV seasons!) and ultimately, the running thread of the Reapers added nothing to the game. All they had to do was keep inventing new threats - ME1 the Reapers, ME2 a human civil war with Cerberus, ME3... something else. And if they did it that way, they could make new games indefinitely.
Ah well. I'm glad to be done with the franchise and with BioWare. I find it funny that I was so in love with the franchise and its ideas the first time around and slowly but surely, they killed it for me.
I hate that I am OCD enough to want to get 1000 points in the game, which amounts to grinding MP forever to get that 5000 kills achievement, but I guess they put that in there just to fuck with people like me.
Also, the music was bad. I didn't like ME2's soundtrack, but at least it was memorable. Here, it didn't even exist and the only things I remember are remixes of ME1 themes.
