Not sure if this classifies as a console game or a pc game or not a game at all yet, but one of the most charming games I saw at Eurogamer Rezzed recently was Snake Pass which from chatting to the developers is an idea that came about during an internal Sumo Digital game jam as a bit of a break from work on Crackdown 3 and other big titles. It started from someone playing with splines and kind of evolved from there. Appropriate game name for a studio based in Sheffield as well. Anyway it was completely absorbing and entertaining and I really hope they push ahead with turning it into a full game.

Just wish they'd release the demo build they had at the show so I can play it some more
