Halo is my top pick, the first three have great stories and couch co-op if you need that, and if you get the master chief collection (halo mcc), the multiplayer is great and you can find tons of forge mode maps created by people, from race modes to mini golf haha

Gears of war is also fantastic, epic story, fun gameplay, and who doesn’t love a chainsaw bayonet lol

Deep rock galactic is another really fun one, I can’t say there’s too deep of a story too it, but it’s endlessly repayable with all the combinations of weapons and procedurally generated missions.
