Had some lockout casualties and have 3 teams available to take over in a very deep and challenging league. It's 30 teams with a lot of elements built into it to create a realistic NHL GM experience.
Most people that join the league say that they wanted to create something similar. That's how I got started as well, joined one that flopped so myself and another commish put the work in to create one. Now we have an active fully functioning league that will be around a long time.
