I finally tried the demo last night and it ended being a lot longer than I thought normally. Not that its a bad thing, although I did get to bed much later than I was anticipating.
I really enjoyed it a lot. The combat was very fun and I was just fine with the graphics. I actually like the colorful backgrounds than the more subdued tone. I didnt notice it as much in the tower, but outside everything was alive and jumped out at you.
When I was playing in the tower portion, the game ran flawlessly. I couldnt understand where the bugs and glitches were at that everyone was talking about in regards to the demo. Well, I did find out eventually, basically after talking to Argath. Thats when many things started to go wrong. I could still run around and attack just fine, but I first lost background music, then it was sound effects (no one responded when talking to them, couldnt hear the crates and barrels exploding, no more footsteps, etc). But the worst was when I would talk to an NPC (who gave dialog options), you not only would not hear their voice, but when you picked an option in the dialog, the text just zoomed by. Meaning, it appeared and then disappeared almost immediately. So I couldnt even read what it said.
That being said, with all the issues there were, from what I understand the demo was an earlier build and if all these problems are contained only to the demo then I am ok with that. It gave me a good intro the game and I know I will enjoy it.
Oh, another thing, the employee at GS was telling me that you receive some extra items when starting a new game (from the retail version) when completing the demo. However, the demo never asked me to make a save of any sort, so Im not sure how that information would be taken when I do start up from the full game. Or was the GS employee just wrong?
