Join the HHABL (High Heat Arcade Baseball League)! Why is it called the 'Arcade' baseball league? It's all in the rules, my friend.
First off, you can be any team you want, whenever you want. You don't even have to be the same team during the same series! Be the Yankees in Game 1, the Devil Rays in Game 2 and the Indians in Game 3. We don't care! We just want to have fun!
Second, you can play the games whenever it works best for you and your opponent (as long as it's sometime during the week your scheduled).
Third, you are trying to beat other people, not necessarily other teams - that's why you can use any team you want. You're not just the Mets versus the Phillies; you're Pete versus Scott. The winner at the end of the season is a person - not a team.
Sound good? Great! Read the rules, sign up and play! Good luck.
