I am bored so I play Candy Crush Soda and windows solitaire.. not needing much to play. But it is really just a chore.. click click click click repeat.
I used to play Sims quite a lot, also SimCity.. but I am quite disappointed with the latest versions, and same thing with Spore.. what a buzzkill. I am waiting for RCTWORLD but I feel I have too high hopes but you never know! RCT1+2 must be my most favorite pc game ever. (as opposed of console games)
RCT3 was too buggy (and too slow when you trying to get realistic size park)
Of course sometimes I test games (there area few gems) and also my own games but it is not really same thing when trying to find bugs and play through levels you know already about.
