Funny thing, I've also been playing Pokemon (White/Omega Ruby) and Assassin's Creed (3/4) in my free time, as a way to relieve the stress.
I should be focusing more on my Master Thesis before even dreaming about a possible PhD, but the anxiety is killing me. Maybe I will try some Nuzlocke challenges in Pokemon and see if I can transfer part of my real life pressure to the game
