It is fairly shallow for a small collection, but it is also boat loads of FUN. It is very much like Monster Bash in this respect. I have had the game for about 5 years now and it was the 5th game I purchased. I did initially get pretty bored with it after about a year and came close to selling at one point. I'm glad I didn't, because it still gets tons of play when people come over and I have come to appreciate it more now that my collection has grown. It's just all around a great machine. An ehanced ruleset could make it one of the greatest games ever.
