I would play my DS, or PSP... either that or Halo: Reach, depending on if my dad is home.
If you think an hour is bad, then you're lucky that your system doesn't simply delete random files every so often (it's very old, and its memory storage is corroded, so it has trouble keeping data intact). My record is having to format my computer three times in a week. Luckily I got it replaced a long time ago, but it still haunts me.
