I'm a vet of the ATG as well as this game. I'm also a member of the F.O.D.L. a Strat Simulation Game where every Franchise is owned by a manager in a dynasty league. We are completing 1971 and will be starting 1972 after our playoffs. There will be a draft for 1972 eligible players.
A new member should have an interest in owning a franchise and be interested in the 1970's and hopefully the 1980's. The FODL began in the early 1960's so there are a lot of veterans.
