Especially lately. I've got close to Valinor a couple times in the last few weeks. STRESSFUL!
But still a feeling of accomplishment, just getting somewhat close.
Bottom line: I can play for fun, or I can play competitively with my mind made up that I want to get to a wizard mode like Valinor, BFTK, or Portal, and failure to get there is stressful.
Of course my best games are always when I just play for fun! Then they get stressful towards the end. lol
