Tibia came first than Runescape brother, as the years went by Tibia became more active than ever, it might be a bit slow to advance in the game, but then you will have a lot of fun when you get to the world of the premises, as you will be able to do millions of things more and thousands of dangers to discover.
I never got to play Runescape, as many of those who played it moved to Tibia, I guess the game has a lot of critics, but the important thing is to enjoy them.
