Dan, I don't understand you... is like saying you like better a CD-R than a a DVD-R... if you get what I mean.
Have you actually played Evolution in all of the modes? Have you seen all the guides and tutorials this new game has? Have you seen all of the improvements QUEST has over KUMITE?
KUMITE was only a matter of fighting and going up in rank. By random, some items would be given to you.
Then QUEST has those elements, but much more. You get to choose what you want to buy. You get to choose how to beat oponents depending on the order quest you choose.
In other words, this game is much more fun given the variety it has. KUMITE was cool, but it got reppetitive and boring after a while. QUEST never gets boring. Is one challenge after another, after another, after another
