There is a store of sorts where you can redeem your points for various things like sweepstakes entries, gift cards to various places like McDonalds, and donations. I just get MS points for my account to pay for games. It's like $1 per 1000 points, but a few weeks ago they had a special, a $5 gift card for 4k points. I figure I can redeem about $5 per month doing all those game pass quests and whatnot. It's kind of fun in itself too. At least for me, whose personality craves explicit goals in gaming.
Weird thing, I get actually disgusted when my friend Mark plays a game just for the fun of it. I gotta stop that.
