The world of gaming isn't entirely made up of safe sequels and predictable adaptations. Some developers choose to step outside the mould, resulting in games that are unique and totally brilliant. Of course, following this path has also resulted in some of the strangest, most outlandish games ever made, that were just never fit for mainstream success. Games of this strange calibre unfortunately seem to be getting rarer as the games industry matures, although indie gaming in particular has made for some delightfully bizarre gems. While many of these oddities have ended up as total disasters, nobody can accuse the developers of making a simple cash grab. In rare cases, these weird titles have even turned out to be some of gaming's greatest masterpieces, with the uniqueness only adding to the experience. This list takes a look at some of the weirdest games ever to be released, featuring gameplay and narrative unlike anything else out there. From bizarre simulators that require insane peripherals to shoot 'em ups with ridiculously inappropriate enemies, you simply won't believe that some of these entries could possibly have ever existed.
