I know there's a bunch of others that people can think of, but when it comes to being consistent across the board, these games are a blast. I think it should be up there with their top franchises because the design is so timeless and perfect. Not only are the characters funny and full of flair, the joy comes from figuring out the boxers' patterns until you eventually find ways to take them down faster and faster. It doesn't get old.
It was fifteen years between Super Punch-Out and Punch-Out Wii. Now, who knows when they'll attempt another one. There really should be one per gen. Hate to see Little Mac regulated to being a Smash character for the rest of his existence only. I know Punch-Out Wii only sold just over a million or so, but they shouldn't let this series be down for the count.
