Enjoying splinter cell at the moment, the extra touches with the gamepad are really nice, quickly changing between weapons is a great feature. Also access to whatever challenges are up on that day, not essential by any means, but useful none the less. Graphically it's fantastic as well, can't really remember enjoying a splinter cell game this much since the days of the original.
Wonderful 101 I feel will take some getting used to, a rather big learning curve. I think once I've gotten to grips with it I'll enjoy it a lot more. But so far it's definitely an interesting game, something a bit different to have a go at.
Street fighter on the other hand has just taken me right back to the good old days of playing on the snes, love a bit of nostalgic gaming. Though I remember being a lot better at it back then.
