ManaPlus 1.6.2.27

ManaPlus is a 2D MMORPG, originally inspired by the fantastic Secret of Mana-games. Besides traditional mmorpg-gameplay it has absolutely fantastic 2D graphics and is amazingly polished. Fans of the genre really should check this one out, it's a very well made game. ManaPlus is a client for The Mana World and Evol Online, so those two are also options if you want to play this game.

Truly beautiful 2D graphics - and a great looking GUI as well.
