Aura Kingdom is a Free to play “Anime MMORPG” I have played this game myself and I admit I did lose interest and stopped playing at level 49. But, it is a good game and worth your time if you like MMORPGS.
If I have joined a guild or played with some friends I know I would stayed longer. but I played it solo and got bored doesn’t mean you will though. check it out and see what you think.
one piece of advice try a few classes before you settle on a char to level to max so play to 20 and try a alt.
