I would play with my dick
I never knew 'my dick' was an Amiga game, I'll have to try that one sometime
. Anyway to start with I thought this was a really hard question. Then I realised two hours isn't enough time to play some games properly, like Settlers or UFO or Monkey Island. You wouldn't really get anywhere. So, considering I've only got two hours and must play an Amiga game I'd pick something like Superfrog, Qwak or Ruff n Tumble. Nice and simple to play and distract you from doom.
