You know, Rift is a good game. It plays well, it's very intuitive (especially if you're from a Warcraft background as it's basically the same game) and it looks great.
But in the end I found it somewhat boring. Uninspiring, even. It looks great and the backstory is wonderful, but it felt like I was simply walking from drab location to drab location twatting enemies. There were no moments where I found a location and marvelled at the imagery, like I did with Ironforge in WoW or the dwarven realms in WAR. There was no 'Cor, look at that!!!!' factor. It was a good game to play but was ultimately rather dull for me.
But don't let that put you off. My wife still plays Rift and she's loving every minute of it. If Star Wars: The Old Republic wasn't coming out I wouldn't have cancelled my Rift subscription, to be honest. Give me the choice between swords and lightsabres... sorry. No competition, really. But that's a matter of taste, not quality.
