I don't even agree that ME 2/3 are excluded. Definitely above the rest they released, but 2 was already meddled with, stripping away a lot of the RPG mechanics to turn it into Gears In Space and introducing absolutely retarded concepts- like one-use disposable thermal clips.
ME2 was still good, but still negative compared to what came before. ME3 was more of the same- though I will say that it's how they handled previous decisions that were supposed to be impactful as just a couple points on a board, while stripping out crew, and that abysmal ending.
