Tomb Raider Underworld: I enjoyed everything about this game except for one thing...collecting all 179 treasures. It was a pain! Your first play through will eat up some time due to the treasures. I did it on easy first, then replayed it on Master Survivalist for the final achievement. Second play through on hard only took a few hours, maybe 3. I've never been a big fan of the Tomb Raider games, but I had a lot of fun with this one. I highly recommend this game. There were a few bugs I did notice, Lara will get stuck in the ground a lot. What you must do if this happens is just shoot. Another strange bug was an invisible Lara, needless to say it's very hard to jump around on poles and whatnot when this happens. Hopefully the upcoming downloadable content doesn't have you collect a bunch of garbage for achievements. If you do play it, see if you can resist picking the short shorts jungle outfit 100% of the time.
