Based on personal experience from an average gamer.
Games not to get
*Assassin's Creed : Brotherhood
-Slow / Hard to get used to
*Devil May Cry 4
-Lots of bugs
*Saints Row 1,2,3
-Pointless/not much people online
-Bad sound/audio interpreters
-Storyline is crap
-Takes atleast 6+ seconds to kill an weak enemy
-Easy 2 mess up
*Need for Speed Shift Unleashed II
-DO NOT GET THIS AT ANY COST. I wouldn't even get this for free. Total rubbish
*Super Street Fighter IV Arcade Edition
-Anime style graphics with crappy cut scenes
-Slow and uncreative gameplay
*Dragon Age II
-Good game but easy to get lost
-Hard to get used to / easily mess up
-Uncreative medieval storyline
-Normal FPS, nothing unique. Cod is much better.
-Maps suck at multiplayer they are RIDICOUSLY huge.
-Not fun because you can't reach enemy base without being shot due to large maps
-lame weapons, storyline, gameplay,graphics everything .
-Bought this for $4 on steam and regret it.
