Wait... some people besides me like Myst? And here I was thinking that the entire GOG community was bent on its systematic destruction!

orcishgamer: Or maybe SPAZ (time warning on this one).
Runehamster: That's actually a very good idea, Orcish. I was looking for something kinda stressfree to play. Crayon Physics is good too, but I own SPAZ and hadn't played it in a bit.
Stress free? Hmm... Crayon Physics is honestly about the best choice I can think of. It's one of those immediately endearing games that defies all criticism simply because...awwwwww! Depending on what you find stressful, Osmos might be a good choice as well.
Oh, of course...Trine would be great! It is the single most charming and endearing game I have ever played. All the sort of whimsical magic of a fairytale, but not in a gooey way. Be warned, though... its physics can sometimes be a little wonky.
Oh, and of course there's always Minecraft on Creative mode. Or just some good old Doom or Quake... nothing says stress relief like blasting away hordes of monsters with a shotgun!
