Mass Effect 1 LE > Mass Effect 2
I always remembered ME2 being the greatest game of the series, but damn, going back to it, there are just too many enemies. It's not hard, but sniping 2 dozen blue suns coming out from the same bathroom gets tedious after awhile. Levelling and RPG mechanics are more interesting in ME1 too. If ME1 had Mordin it wouldn't even be close to being close.
