Space simulator games like Wing Commander and X-Wing helped shepherd the genre through the ’90s, but it wasn't until FreeSpace 2 that a real narrative was attached to all of the deep space mayhem. An offshoot of the Descent series (see No. 19), FreeSpace 2 put you in the ship of a rebel Terran (no relation to the StarCraft race) fighter pilot 32 years after the Terrans sold out and allied with the traditional enemies, the alien Vasudans. Heavy stuff, for sure.
