Have fun, and try to not worry too much about us! I could go on with this "Minecraft > life" joke, but I actually think life is quite pretty
She's not lying. Its real. Its not a very nice place, but its real. The gameplay is great. Think Sims but in first person. The physics suck though and there's way too much micromanagement.
Ive been to Mexico a couple different times, hope you enjoy it. Be safe and have fun Drink bottled water as much as possible or take along a water filter...sound crazy but works.
