Any Mmorpg's with long play without getting bored!

That's pretty hard to pinpoint; it really depends on the kind of MMORPG you like. And ideally, the best way to make any MMO more lengthy is to have friends to play it with.

Well... I played WoW for a long time without getting bored. But some people hate it.

It's a matter of preference.

If you're looking for cool quests and story, tho... I'd recommend The Secret World. The gameplay isn't the best, sadly.

If money is not an issue, I would take a look at ArcheAge's Founder's Packs. Several traders sell them for around 50% off retail and they accept TF2 keys or PayPal.

or

You could just play DOTA or LOL if you're into MOBAs.

ArcheAge is a good one

I'm not into MMO's, but cant you just move to another game when you get bored, I've been doing that for years with good results.

Teeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeam Fortress 2. God I love that game.

no.

Star Trek Online if you like Star Trek

Be it 5-6 years ago, I'd suggest FlyFF. Now I'm not sure about it anymore; I quit because I actually got bored in the end, I think. But hey, it was a lot of fun back in the days.

Guild Wars 2, as for free to play maybe Tera, although Tera can get boring with the same "kill x number of y enemies"

I played Swtor for ages and it's storylines kept me interested for a while. The endgame is lackluster though.
