At the moment? Tera and Guild Wars 2.
I played the Tera beta….It's pretty fun. Game looks amazing, but when it comes to questing and stuff it adds nothing new. It's just "hey go do this, pick up this, etc etc."
The catch is, the combat is all action based. No RNG stuff where a rice roll decides whether you miss or not, and you have to manually aim all your abilities and attacks, and dodge out of the way in time. It's kind of like the Souls or Monster Hunter series.
Guild Wars 2 is really similar, emphasis on pvp and whatnot, and it's all action based. If it's going to be anything like the first Guild Wars, it's going to have classes and quests out the ass as the game gets older, so you'll be occupied for quite some time…Oh not to mention, it's not gonna have a subscription. :)
