Yep. I wanted to do Renegade and I still may someday, but the reason I saved everyone in Mass Effect 2 was just because I did all the things. I wanted to experience all the game has to offer.
My understanding is that during the final mission, you can designate a person to do a thing, and if you haven't completed their loyalty mission, they fail (or, they can fail) and if so, they die. But, if you've either done all the loyalty missions, or you've done the loyalty missions of those you send, everyone lives. I may not have that 100% correct. I mean, I've only played ME2 the one time, and it was last year. (I could never get through the first one.)
But yes, fuck EA. It's harder for me because I remember when EA itself was good. I had a paint program on one of my first computers, Deluxe Paint (developed by Dan Silva, I still remember his name from the splash screen) and that was made by EA. Except it was just "Electronic Arts" back then. Activision made their own games, too.
