The "Instant Adventures" and dynamic events like rifts and invasions combined with a flexible class system make this one of the best MMO's out there.

Action combat, NPC followers, quick and easy matchmaking, this one is surprisingly polished and tight. It nails the formula; one of the best F2P's ever.

Instead of simplifying and streamlining like WoW, EQ2 went the opposite direction and kept adding layers of complexity. Endless possibilities await.

The first version with online co-op, it's an RPG/RTS hybrid. Create a custom hero, gain levels, skills, gear, gather followers, raise an army. It's fun!

Different classes with skill trees, customize your companion's abilities, interesting loot, and screens full of enemies to take out solo or co-op.

Turn based battles with an organic feel, dynamic environmental and elemental effects. Multiple-choice dialogue options, adventure, and it's co-op!

More Baldur's Gate co-op goodness, now with D&D 3E rules. This is the definitive version, with widescreen support and online multiplayer.

The best co-op FPS ever made! If you want the first two chapters, this is it. It also has new game modes like survival, and Steam Workshop support.

Co-op FPS tower defense. Build your maze, arm it with turrets, missiles, lasers, upgrade your weapons, and slaughter the oncoming hordes. It's fun!

More vehicles, more weapons, more customization, and superpowers = co-op heaven! but Saints Row 3 is still the gold standard for urban mayhem.
