I have a confession to make: I have not played a game online 1-v-1 in ages until SMB 4. The pennant race is fantastic: online, cross platform and quick (5 innings with a 10 run mercy rule).
There are very few games that allow you to play as 1983 Orioles World Series MVP Rick Dempsey, but SMB 4 does.
This game is a complete blast. I suck at it, being 1-3 rated 1990 in the rankings..but boy it’s fun. Naturally, Glen and Craig won’t play me.
