Sorry guys, found some more Vita stuff to post, don't think it's been linked in here before. I'm having such a Vita-busy day today!

Some AC3: Liberation gameplay. This looks like console Assassin's Creed to me. I'm really impressed with this game.
And secondly, some gameplay of PSABR being played on Vita - it appears to be running really, really well. No framerate issues or anything I could notice. Colour me impressed (will be another game I'll have access to with cross-buy!)
