Ok, dont get me wrong. I think ME2 so far is a solid game. Its just.. my personal description of the game would be "Gears of War with a sprinkle of BioWare RPG on top." And I really do mean sprinkle. Its no where near like ME1 in terms of RPG. However, again, its a solid game. As for conflicts and troubles the only real problem ive had is I had to turn off mouse smoothing using notepad++ (cause they use something funky for the ini files and wordpad or notepad editing will make the game crash)
If you liked Gears of War, and you Like Bioware's dialogue choices, and the Mass Effect universe in general. Then the game is probably for you.
I myself wasnt a fan of Gears of War, and im not feeling as addicted to this game as I was ME1. But thats just personal preference. =)
