This game actually is Worms United, which combines the original Worms with the Reinforcements expansion.

Classic hot-seat multiplayer, turn-based annelid action.

At a quick glance this may look like one of the countless fantasy RPG games with wizards, orks, trolls and goblins, but once you start playing you realize it's a fun action game with a nifty magic spell combination system and brimful with pop-culture references and allusions to many other computer games.
With some of the DLC packs it even gets wackier with the addition of Vietnam War weapons like machine guns or Star Trek style phazers.
Magicka is the perfect co-op game, both online and local.

A very straightforward no-limit Texas Hold 'Em poker game.
That is, in respect of the card playing mechanics. The characters you're playing against are far off from straightforward.

It's hilarious to simply listen to their comments, reactions and small discussions they have among each other.
And if you know them from their respective computer games/media they're coming from, it's even more fun when you get all the in-jokes and allusions.
