Ken Griffey, Jr. Presents Major League Baseball
Slugfest will pack plenty of baseball into the little Game Boy. It carries full MLB and MLBPA licenses, so you'll get all the pro players and teams--and you'll be able to cut trades, too. The gameplay will be standard 3D-overhead view baseball with players tuned to real-life stats. You can play head-to-head or team up with four other gamers. The only strike against Griffey may be that it's for the Game Boy Color only.
