67. X-COM: Apocalypse (Mythos Games, 1997)
Just one game in the long-running Worms turn-based warfare strategy series, and the one widely regarded as the best in the franchise. Unlike many of its sequels, it gives players the option to have teams larger than four worms (six or eight, depending on the number of players in the game), allows for custom team voices and terrain to be imported and has just the right blend of weapons, gadgets and options to make for lengthy, yet engaging online battles - from airstrikes to poisonous skunks to flamethrowers to Street Fighter style martial arts, you won't be wanting for ways to lay down the pain. Not to mention that it's always more fun dropping a concrete donkey on a bigger group than a smaller one, of course. A standout in the turn-based artillery combat genre.
