So, what got me thinking about this is Namco Museum DS. I never would have even considered owning this, as I've already got enough variants thereof. However, a few years ago, I saw it on sale and decided to read the back, and was surprised to see a portable version of Pac-Man Vs. included. I love that game, and it offers single card download play. No brainer for me.

Any games anyone can think of that people might want for odd reasons the developers/publishers didn't play up or weren'ttalked about much? I know I bought TMNT Battle Nexus for its having the arcade game included, and several Sga Ages 2500 releases because they had multiple regions' versions of classic games on them. I know a lot of people like Donkey Kong 64 for the arcade game's inclusion... what are some more games with modes or extra games that make an otherwise bland game into something more special and worth owning?
