I used to play Tibia nad Runescape, but both are horribly unbalanced. Tibia with unbalanced voacations (A level 8 wizard has an easier time then a level 20 knight), and Runescape with unbalanced levelling (Death at level 8 to a level 2 goblin).
The only MMO I have fond memories is Everquest. People were actually NICE to me. If you go out an say you're a newbie in Tibia, you better hope you're not in a PK server. I go and say I'm a newbie in Everquest, And one guy pretty much gives an advanced sarter kit of armor and weapons (which I was mostly too low a level to use), and another guy just gave me money, because he felt like it. Only thing I had a problem with Everquest was when one guy started ****** because I was killing goblins in the same area. MMO players like to take temporary ownership of places it seems.
Tibia brings bottom of the gutter though. Even on the newbie island, people can be complete ****. I was trying to train with distance weaponry with spears. Using a spear causes the spear to end up underneath the monster you threw it at. Well, some guy has the bright idea of taking said spear, and then tries to sell it back to me for double its price.
