Can I say that I cannot stand ME2 and, in fact, it was the only ME game that I played once?
This for one simple reason: it’s basically a SIMS game. ME started with a bang: an interesting investigative plot! It dropped you in the middle of an urgent under-explained situation and poked at your curiosity to discover more, there were responsibility to approach, a world to discover and conspirators to undercover.
Then comes ME2 that’s basically an errand boy simulation: do chores for an obvious bad guy (come on… “Illusive Man”? Who thought that was a good idea?).
So now you have to ping in a never-spoken-before fringe region and have to recruit a bunch of people that ALL HAVE THE SAME BACKSTORY (Conflict with a “fatherly” figure… Except for Thane whose conflict is not being a sufficiently good fatherly figure) and, while you are there, be nice so you pork them (the camera placement of every Miranda interaction… Aaaargh!).
Tali in ME1 was a young curious explorer with personality and confidence… In ME2 they “damseled” her so much that she said it out loud at the first encounter… And don’t make me start on Ash!
I’m sorry but for a “Series Pinnacle” the only thing to learn how NOT to write plots and characters. But since ME it’s a massive Kirk Power Fantasy for sex-obsessed Gamers then yeah! Best game ever!
