I just played through Unseen Diplomacy. It came out in April, but I didn't have enough space to play it at the time. It's really amazing if you have 3x4m to play with. Movement is entirely roomscale - there are no buttons to turn, move, or teleport. You must physically turn, walk, crawl, shimmy through the game. Its very immersive because you never have to think about where you are in real life, as the game is designed to always keep you within your playspace. It's quite a short game, but is only $3.29 cdn.
