On the subject of GW2's endgame, I can agree that it's missing something. I quit a few months after I capped.

You should still try it. The dungeons are challenging and the game has alot of events, but you're mainly working for transmogs once you get your crafted set. While I think a progression system to WoW is outdated, there has to be some progression. You'll hit your stat cap really quickly, and if you're like me, you won't want to reroll because it's hard to 100% everything in PvE a second time, but it's useful for some of the harder to obtain transmogs.

With that being said, if you like PvP, GW2 is, unquestionably, the game for you. Even the easier dungeons like ACHM can be challenging. The set looks good too. At least the weapon does. Beyond that, maybe they added more things to keep you busy, but the game has a strong community regardless.

Tera has a strong (at least populated) community too. It's an alright, but not innovative game aside from the combat. The pacing is ridiculously slow at times, considering that the reason you probably bought Tera (when you could 'buy' it) was for the combat. If you want PvE, that's pretty much the game to get. The endgame progression is a little murky, though. Enchanting is ridiculous at times, and if you're not in a good guild, grinding gear can be a pain (dailies are boring, but the nexus event was fun, if you can catch it).

Wildstar's another good one, though, I personally don't like it. The combat's good. The graphics for good. The game's revolutionary, but I feel like they should have developed it for another year. Polish is important if you plan on living in a world.

I don't recommend touching Archeage either, with coming titles like EQ Next (very promising) and Skyforge, which may or may not see a beta early 2015 and has a unique concept. The combat looks good, too, but I can't really speak for the game as I haven't played it. The whole overwatch superhero-minus-spandex theme looks awesome though.

Speaking of superheroes, Champions Online is a good game. It can be frustrating at times, and I'm not sure what has changed in the past year or two since I've played it, but I do remember hitting the burnout wall like... a brick wall.

Honestly, I'm just waiting for Lunia 2. I know that's what you're doing from all of the money you're making off of Kritika, allm. I'm onto you.
