EVE Online

I've played World of Warcraft, Lineage II and Ragnarok Online, and a few other really shit korean MMOs not worth mentioning, they all really disappoint. WoW took the longest, but really, it's such a grind, they all are.

I'm looking for something 'different', and when people describe EVE Online, I often hear 'different', it looks interesting, but then, so did WoW...

Why should I play EVE?

Why shouldn't I play EVE?

I hear EVE has a huge grind as well, but it allows you to be a cool spaceship.  That's it.
