MMOs in general tend to be pretty stressful to me, sadly. I really enjoyed exploring the world and story of Vana'diel for the time that I was playing FFXI, but I'd get stressed out by all of the things I needed to do to be an adequate player. :laughing:

Besides that, I've heard that Pikmin 1 is pretty stressful. Trying to get through MGS1 without being seen was pretty stressful too. And trying to keep my pikmin from dying in Pikmin 2.
