It's also quite nice being able to explore new places when you're agoraphobic! In spite of living right next to woodland I prefer to explore the woods in video games because there's less "argh outside" about it.
and less spiders. there's also less spiders.
Best part about exploring a fake world instead of the real one is that at least the fake world gives you the tools to deal with itself (hero in a box, anyone?). Wish real life was half as close to that...
