Now onto my
idiotic and probably in the wrong forum question. If I buy To the Moon online, is it a physical copy mailed to me, or something that happens instantly online?
Where are you buying from? If from Amazon, you will get a physical copy. If from Steam or GOG, then no, just a digital copy. I don't know about GOG since I don't use it myself but with Steam, you can download and reinstall it as much as you want since the game will be tied to your account. I believe it's also only a digital copy when you buy directly from this website, but again, I'm not sure.
