You don't actually have to buy the game to register, but if it's still a problem for you, the cribs note version seems to be this: a lot of people are having issue with non-adjustable IPD. I think there's one person who's not and is really digging it. So while it seems they've made improvements (one eye bug is gone), I wouldn't buy a Rift solely for this game until it gets more unanimous praise. Looks like it still needs some adjustments.
