I finded mabinogi and I saw some post about it around. I was wondering if I should try it or not ?

It's a pretty good game if you aren't bothered by anime graphics. The story is pretty garbage and broken, just like most MMOs, but a lot of us play and it's got some of the absolute best combat and skill mechanics I've ever seen in an mmo. Give it a shot, and get on Mari server. Let us know what your username is once you get going.
