With the current number of players seemingly decreasing, I'm actually ok with allowing multi accounts with a few limitations. I'd say if someone wants to manage two accounts, go for it. Any more than that is a bit odd. If you want more fighters, buy fighter slots.
I also feel managers should be able to have multiple businesses. If there's a motivated manager, he/she should be able to have multiple businesses.
This latest catch was a good one, though.
Just my two cents.
