Just downloaded Vindictus, it's a freaking blast. The graphics are stunning, the gameplay and physics are very crisp, the community is great, and this is all from a F2P game. The game was created by Nexon and Devcat, I was skeptical about Nexon, but they really did a great job.
I encourage those to at try this game, if you're into dungeon crawling with a Dynasty Warrior combat style. For being F2P, it's rivaled my gametime with even WoW, that is, until 4.01a.
But seriously, I would give this game a go, you may be surprised.
