Don't Judge By The Demo!
I have actually played the game itself with an OPEN mind and WITHOUT comparing it to any other game. In reality, when I play a game I never compare it to any other game. My opinion of a game is that of the FUN I have as if I have never played another game in my life.
IMO this game has a nice story, nice graphics, great music and sound, a very nice variety of "worlds" , great game play, great variety of weapons and armor, interesting skills and the best fighting I have ever seen in any RPG game.
So this is what I recommend. Play the game (not the demo) and do not compare it to any other game while playing. By play I mean actually play the game for a nice time period...not something stupid like an hour and decide you don't like it. There have been rpg games that bored me for the first two hours and then...BAMB! ...they start to get really good. So give it a honest try...and if you are having fun...that is ALL that matters right?
