One of the best kart racing games on Steam. The coop mode allows players to unlock new tracks together. It offers 4 player splitscreen.

This is a nice family game made by former Rayman devs and mixes jump'n run with beat'em up genres.

Sadly the player base is too small to really recommend it as a MOBA but it is a fun and unique split screen game to play with younger kids against the AI.

Orcs Must Die 2 is an unrivaled tower defense game. It has great humor, is easy to pick up and has coop at it's core.

This game is a classic and still recommended today. It's a coop tower defense with FPS and RPG elements and very fun to play with friends and offers 4 player splitscreen.

Iron Harvest is a very enjoyable RTS, based on the area control board game Scythe. The story can be played coop and of course there are also skirmishes against players or the AI.

Fun game that mixes factory building with tower defense.
