I never played the first, and I just have to say WOW this game is amazing. I feel as though I bought this brand new at the quality of gameplay and graphics. It's like Baldurs Gate meets City Of Heroes. I love it.
Reminds me a lot of Neverwinter Nights as far as the game engine goes. Neverwinter Nights meets 1960s DC Comics cartoons (or the Adam West Batman show). A match made in nostalgia heaven. =)
Found the original in a thrift shop for $2 complete in box. I had to hunt down the patch and tweak a couple settings to get it to run, but it was completely worth it. Bought the sequel here the same evening.
