Yeah, I have a few recommendations! I haven’t done peer to peer intranet connecting, but I have done the multiplayer for these games that are pretty accessible price and resource wise and are fun to play with friends:

• Rocket League ($0) - a fantastic co-op or versus game involving a neat concept of rocket powered car soccer. It may take a while to get use to the controls/concept, but I’ve sunk a large number of hours into it! It also has a pretty good training mode and AI exhibition matches to get you up to speed.

• Marvel Rivals ($0) - a new release hero shooter in Marvel Comics fashion. Has some teamwork and strategy in its 6v6 games and is an accessible into into hero shooters.

• Portal 2 ($10) - one of my favorite games ever. Its a story driven puzzle game involving spacial vending portals. Can be played co-op and it a very fun experience single player or with others.

• Overwatch 2 ($0) - see marvel rivals, as this came out first.

• CSGO ($0) - a classic multiplayer shooter with a long time following.

• Helldivers 2 ($40) - modern bullet hell Coop shooter against lore specific aliens and robot enemy hordes.

• Battelbit Remastered ($15) - battlefield-esque shooter gameplay with big maps, small battalions within larger teams, and vehicles. Indie dev.

• Ultimate chicken horse ($15) - a very fun single device coop thats a combative platformer. Great with groups, and it says it supports online play.

• Divinity Original Sin / DOS2 / Baldurs Gate 3 - all fantastic co-op fantasy RPGs that can be paused and picked up whenever. BG3 is the most recent and is very well critically acclaimed.
