Rift has advertisements everywhere, there isn't a black corner of the far net that hasn't been posted in Rift ads.
But besides that it's hilarious "We're not in Azeroth anymore". Ha.
The game copies point for point every system WoW uses without altering virtually anything.
But I digress, Rift was fun from the beta I played, I enjoyed the higher paced energy regen as it made Rogues more fun at low level than WoW's but the casters seemed... Lacking?
Maybe I'm just biased because Fire Mage in WoW is the pinnacle of casting. Replicating the particles and procs isn't enough to capture what I do with my mage so I'm not sold there.
I didn't get into any instances so I can't comment on end game.
The world events were fun while the novelty lasted but really I was sick of them in a couple days.

The graphics are better but I prefer WoW's Aesthetics, much stronger color palate in my opinion.
Plus I think Blizzard has more experience making relevant information apparent, Rift's graphics make it seem busy.
All that is besides the point, those who play WoW will continue to play WoW, I saw Rift as a polished but ultimately redundant re-skin that lacked the social ties WoW has.
If you enjoy Rift I'm happy for you, it's good, it's just nothing new.
