Rift was pretty buggy in Early Access, which was only 5 not 7 days, and had less people that this game will have by tomorrow.
And I'm certainly not complaining that I didn't get in on the first of two extra days that they tacked onto a five day head start that they could easily not have had at all. And last I checked, I haven't paid for a subscription yet either.
Launch is on the 20th, and I have a feeling that it is going to be ultra-smooth and satisfying. As is this delicious cake.
