I feel exactly the same way, chess and other complex strategy games are more work than they are fun for me. As someone spends a portion of the day thinking and solving problems as part of my job, I prefer to unwind with other hobbies.
I've found Blitz to be an effective way to unwind. It's sort of like playing GTA Vice City or Counter Strike and unleashing some mayhem on the board. There's not much time to think too long and get exhausted but enough time to feel deserving of the victory or defeat
If you just want to just have fun I find bullet to be the best.
