Many MMO'S and other multiplayer games. WoW does it for sure, with gear that needs to be crafted or items for gear that you need to hold on to for a future item. Many rpgs with crafting systems put them behind a timer despite completing everything you need. One shooter I think does this is TF2, with their own crafting system. Warframe also does this, but that entire game is behind timers. It's also free, but I don't see how that translates to getting gear.
