Just played Episode 1. My points are:
+ Great atmosphere just like in a JP movie
+ Dinos look right and move right
+ good story
+ interesting characters (while i don't understand why the changed Hardings likeness known from the movie)
+ great soundtrack and sounds
- Graphics are nice but could be MUCH better nowadays.
- just too easy for my taste. The riddles could have been more difficult.
- Episode is a little short
So overall i am pleased with the game but it would totally rock if the graphics would be more up to date. This way it allways has that b-title feel to it.
