So I'm finding the games that last the longest in my collection are those that do not have a heavy focus on "traditional modes". Some of my favorite games are Attack From Mars, Bram Stoker's Dracula, Congo, Fish Tales, and Metallica. With a game like Attack From Mars the saucers are kind of like modes, but they are so repetitive that they don't feel like modes. I'm okay with repetition as long as it's still fun. What other games should I seek out to pay more?
