Unopened: $400 Used: $180 Bioshock's status in the industry is legend at this point - a genre-bending fourth-wall breaker that anyone who favours the original will shout about from the rooftops any chance they get. By the time we'd had one awesome underrated sequel though, it was time to shift gears and journey out from the underwater Rapture into the clouds, producing Infinite; a real head-scratcher with more iconic elements, great characters and one of the best world-designs of all time. From its hulking Songbird statue who you'll grow to love over the course of the game, to the tiny Handyman figure, art books, posters, a small Murder of Crows tonic keychain and the game itself, 2K knew exactly how to capitalise on a franchise with such a dedicated fanbase.
