$1000? for a game? 
Yup. It's a free-to-play game published by an independent developer, so they've asked for funding from fans; the least you can give is $10, most is $1000; you get various perks depending on how much you give, so if you give $1000 you get to design an item that appears in the game.
It's a great game and I plan on giving some money, but a grand? That's stupidity imo
