Do you miss those good ol' NES and Sega videogames? Now you can go back to the golden age of simple 2D games with this title. The Mana World (TMW) is a serious effort to create an innovative free and open source MMORPG. TMW uses 2D graphics and aims to create a large and diverse interactive world.
The Mana World somehow reminds us of Zelda, presenting us with an online multiplayer universe where you can become a hero. There's no linear plot so you can build your own history by making searches, creating deals between players, fighting and acquiring experience.
Obviously, you cannot expect incredible graphics or breath-taking visual effects, but you'll be able to discover the genuine attraction of a videogame genre where adventure and gameplay must be backed up by your own imagination.
