49. Red Faction (2001)
One of the titles on this list that shows its age. Seeing footage of this game in action nowadays is only slightly less painful than being forced to watch a rerun of Friends. Set on a suspiciously generic backdrop of Mars, the game makes the list because of its comparatively robust single player campaign. Its multi-player mode was a bit shit though. Red Faction was considered a PS2 'must own', but 12 years ago what wasn't considered a must have? The game's most memorable feature was a Geo-Mod gun that allowed you to change the terrain and building infrastructure around you. We've discovered where Minecraft got its inspiration.
