"Ragnarok online"
I play this game since two or three years ago. It´s very funny. First you must train to up your level. And them you can make many things, you need obtain weapons, hats, armors, accesorys, ... to killer others player and monsters, bosses ... you can make quest to obtain some objects and you can to conquer castles fighting with others guilds. It counts with six million active users in fifty countries different. In the graphic aspect its very rare, in 2D.
I only play it 1 or 2 months becouse i think that its boring. The game style its very similar to ragnarok but this have better graphics.
"Granado Espada"
Granado Espada its diferent to the rest, you can control three characteres simultaneously. In the graphic aspect it is better than lineage 2 and ragnarok online. I play it only one month in Korean server because it have not servers in spanish. I´m waiting to server in spanish to play it again.
"Ogame"
This game is in a web. Its very very dificult becouse its 24h, you can´t stop it. I play it since one years ago and now I´m top 340 of 4700 players in universe 18. You make ships and them you can to destroy ship the others players.
This is an example to crazy people for ogame hahaha
