Ping Pong.
Table tennis to us folks, released last week. Short and sweet, it offers up the perfect 1/1 experience, the physics are perfect. Played the game a lot in my teenage years, it's all I remember it being.
Don't be put off by the stylization, you'll spend you're time engaged on the game at hand.
In the space of the week the developer has enhanced the game quite a bit on feedback, always a good sign.
You can now set the depth and length of the table, making it much more friendly on roomspace, and enjoyable to play. It is very limited beyond the core game though, all your getting is a simple arcade/practice and knockout cup. No multiplayer.... extras such as custom bats/tables would all be welcome.
Worth a few quid if you like table tennis, yes. Would something of the like rockstars table tennis trump it, hell yes, the game really suits vr.
