What are some amazing free to play online games that won't have you addictive?

It seems like Free to play is the new way to go! I'm seeing more and more of this everyday with amazing graphics! Now when i say addictive i mean that you won't sit there for 8 hrs straight like what maple story does to you. I LOVE MicroVolts however i wish the graphics and more content was available. Grand chase is nice too but the graphics and its 2d. I just found a new game called apb reloaded seems like fun! I play Vindictus too thats amazing. games like these hopefully. I like action games with great visuals. Yes i want to play with people but something with simple lvlings not having to create the ultimate player like WOW. I downloaded S4League didn't like it but will give it a try again. A.V.A is good on occasions. Dragon Nest, played the closed beta waiting for open! Gunz = blah to me! it used to be fun!
