My tenth favorite multiplayer video game of all time:
Worms Armageddon (PC)
There’s a certain simple madness to this game that I can’t resist. You control a team of cute anthropomorphic cartoon worms with a vast aresnal at their disposal. In a twist on the old “gorilla throwing bananas at another gorilla” QBasic game, you have to take many factors into account in your destruction of the opposing team: Wind, distance, barriers, timing, crazy explosion shapes, etc.
I first encountered this game freshman year of college, when it was about all our bare-bones laptops could handle. It broke the ice between a lot of us on the hall, and we wiled away many a happy hour.
As an added bonus, I appreciate the game for taking a surprising amount of brainpower. Crafting that perfect grenade toss to come from behind and win takes both a keen mind and steady hand. And how can you resist the exploding, flying SuperSheep?
