I've mentioned this to the two friends I have who used to play Rift, and both say they will definitely give it a try again once it goes F2P.
I've paid for 1 year subs since the game started, got the collector's edition, and have bought all of the mounts and shit they've had for sale. Best part? I don't even have the game installed lol. My highest level character is like 37 or something, and I haven't actually logged into the game more than a few times to pick up the new stuff I bought. Why, you may ask? I really think Trion is an amazing company, and feel the need to continue to support them. I will play Rift once my friends come back, for sure. But doing it solo just didn't pique my interest since I still had WoW to play.
