I have about $25 in my Steam Wallet. Should I buy a new game or the TF2 Halloween hats. Decisions, decisions...

L4D2 has more replayability, but Bioshock is also a must-play awesome game.

Anybody who hasn't bought TF2, please don't hesitate to buy it. It's one of the best games ever made.

You don't need existing friends to play TF2. Just join a server that's full of people and start shooting other people. You'll make new friends soon.

First day I tried to purchase on Steam I got this error too. So annoying because 99% the fault lies on Steam's side. Their fraud-detection system is really paranoid. Got it sorted out in about 3 days, now I can buy anything I like.

Bioshock isn't scary, but you can get claustrophobic while playing it. There are few open places to explore, most of the corridors also look the same. I got lost several times while playing it. You really have to take note of the landmarks and use the game map to get around.
