I wasn't a bad game...far from it. It just seems like there should have been more. Most of the game was compiled of crew member story missions. After the initial start there were less than a handful of story driven missions then BOOM the end 2 end missions. It wasn't as deep as the first either.
I ask b/c these were things I thought most gamers would have thought were very poor decisions, yet it seems ME2 gets high praise anyway.
