My girlfriend bought MediEvil for me for Christmas 1998, almost a year ago, and I'm still thanking her for it! This game is great, and the only drawback to it is that you will, eventually, finish it. There MUST be a sequel, or I may give up playing video games!
The graphics are very nice, not necessarily the best ever but way above average. They are fluid and well done, though the camera angle can sometimes be looking at Dan from the side instead of from behind him. Mastering the L2 and R2 buttons will alleviate this problem.
The landscape variety is astounding, the different boards are unusual and interesting, yet linked together in a great way. If you look closely at the "sky line" in the background of some boards, you can see buildings that you later enter on other boards - a nice touch. The variations in settings and environment is one of the best parts of the game. When you are done, you look back at the expanse of the game and wonder how they fit it all in on one CD. The soundtrack is spooky and sound effects well done - at times when you are on exposed parts of the world the wind noise is louder. The game does a great job of blending playability with difficulty. The puzzles needed to advance can be easy to quite hard, and often take a lot of thought and a little luck.
The best parts about this game, in my opinion, are the humor and the storyline. The game is clever and funny in so many parts, which only adds to the typical "slash and chop" zombie killing fun. The storyline is wonderful and deep, you find out more and more about Dan and the supporting cast as you travel through the realm. A great game from start to finish!
