Shimmying over from the PC, Demetrios is about to have a Big Cynical Adventure. Told in traditional adventure style, it packs in toilet humour and irreverence at every turn, with a bunch of interesting characters and a distinctly Parisian setting. Hopefully it won't cost more than the $9.99 you can currently get it on Steam, either way it is very well rated and well worth a look.
Updated with the PlayStation trailer, which is exactly the same as the original, just slightly more PlayStation-y, really guys?
UPDATE: The game will launch on Vita on 15th November (scratch that, delayed into December)
