Night of 100 Frights was really cool -- my 5 year old and I (over 40) had the best time playing over and over and over. Mystery Mayhem, well, it's a mystery ... how/why it ever got made... the graphics are poor, story line/presentation is lame, no excitement, no challenge, even my 5 year old played for about an hour and then looked very sad, dejected, disappointed, and hasn't returned since. (Can I get a refund?) I suggest you go blow spit bubbles before buying this game, it will be more fun. Trust me.
