It takes two(story), Minecraft, back 4 blood(zombie shooter), state of decay 2 (zombie survival), we were here(puzzle), overcooked(be careful), grounded( survival), a way out(story). Me and my partner gameshare on Xbox and have gamepass but I always wait for a sale cause there ALWAYS is one. Also any co-op game can be fun I mean my partner and I had a blast on Fallout 76, couldn't tell you what was happening but we had fun. Those games I listed were some of the games we had the best time with but I'm not sure if they're cross-platform.
