What do Clint Hocking and Shinji Mikami have in common? They both left companies they've long been associated with recently, and have both made shooters, but that's not the answer I was looking for. The common thread I see is that they both make heavily randomized action games encouraging improvisation rather than repetition.
In Clint Hocking's Far Cry 2 the player's weapon can jam, cars break down, and the player character has a case of malaria which can act up at the most inopportune moments. Furthermore, the game has a buggy AI, so enemies have a sixth sense for pinpointing your location. While this hinders the game's stealth elements it allows for a sense of anarchic randomness you rarely get in shooters.
