Thrillville: Off The Rails, about as chill as it gets. Upbeat atmosphere, if you have a good imagination you can have fun building and customizing your parks anyway you please, there is
no limits or anything to stress about haha.
Plus it comes loaded with a million mini games that are all really fun actually! Was just playing this about 30 min ago haha.
Also Rockband and Guitar Hero.
Trials HD, I have so much fun just going through the easy and medium tracks doing flips and stuff haha its great fun. Just avoid the Hard and Expert tracks until your ready to gouge your eyes out haha.
