It's OK, I will allow the game to connect to the internet because of magic or science or something. You just can't download/play any new games cuz that'd be cheating!

Now, while my favourite games are (naturally) Final Fantasy games... I think after a few dozen times through it would start to get old. Need something with a bit more longevity. Something that allows for creativity. Something a bit sandboxy perhaps.

It'd either be RollerCoaster Tycoon (2) or Minecraft. I'm not actually a massive Minecraft fan but I think it might be a good fit for the one game ever scenario.
