Played a ton of Mass Effect - did a lot of the optional missions, saved Dr. Tsoni, and beat Noveria. I don't even mind the Mako portions of the game (I kinda like the bouncy physics, but hate how long the shield takes to recharge), but the actual combat is still pretty ugh. It seems extremely random, my AI companions constantly get in my way, and there are times when I'm way more successful by just running around and firing blindly than by playing 'tactical'. The cover system never seems to work properly for me, especially after the smooth-flowing Uncharted 2 combat. Some of the early subquests were extremely annoying in this regard, when I was still underpowered.
The dungeons are also pretty lame, apart from Noveria. Most seem to be just straight lines connecting them, and there are only 3 templates that they use for every subquest dungeon in the game. Music is still godly tho!
