The game was fun but way too short and underwhelming. The only way I can see the 60 bux I spent having been worth it is if the community makes a great deatchmatch style mod that becomes popular. At least I know the next game I buy will have enough content to keep me occupied and satisfied for weeks if not months. Skyrim.
Hence getting a refund after playing for 90 minutes.
Edit: Only game I have EVER demanded a refund for.
