I LOVE ME2. I only hate the semi-obligatory scanning of the planets, so I made a list of what upgrades I still need, how many resources it'l cost me an how many I already have, that way I can stop scanning as soon as i have the necessary resources.
I'm now completing the loyalty missions, 1 more to go and than I only need to recruit tali, do her loyalty mission and I can go on. I'm also gonna do a lot of side missions first before continuing the main story.
I do want to finish it, cause there are new games (the saboteur on PS3, Forza 3 on X360 and Divinity 2 on PC) waiting for me and I've been playing it for almost 3 months now
