I basically agree with ooheadsoo. I am not too happy with the leveling up of enemies and money is ridiculously hard to come by. Actually, money is very easy to come by, adequate amounts of money is what's hard to come by. My spells that I have are not as effective as I would like against enemies, but so far, it's costing too much money to get more powerful ones. I'm also not a fan of the combat system, it's just not my cup of tea.
Now having said that, I totally love the game. I have put over twenty hours into th game, and I have done nothing to affect the main quest. At times I even forget there is a main quest. The side quests are great, I love the open ended game play. But, the more I play the game I am starting to think that the side quests aren't as optional as "they" would have you believe. I can't imagine getting through the game without the strength these quests provide you.
All in all, I think the game is absolutely amazing, it is definately a step in the right direction but not perfect. If you like RPGs or just want to go on a HUGE quest, this may be the game for you. I like it.
