This was good of its kind, but not something I would recommend to people who aren't fans of card games. I guess anything with monsters is going to be compared to "Yu-Gi-Oh" nowadays. It's just that these games are so complicated, I wouldn't get used to them only if I saw them being used a lot before. Also, was it just me, or did this not have any audio? A good song is always going to make something better. I also didn't like the graphics.
Granted, the graphics could have been not so good because there were so many cards to make. At least you provided us with something that might appeal to card game fans. It could use more detail. I'm not saying that things need to be flashy in order to be good, they just to be better detailed. I hope you can take my advice on improvement, but most people like this anyway.
