To efficiently create historical baseball leagues, prioritize combining the 60s/70s and 80s/90s, focusing on a few representative years from each decade. These pairings offer rich historical context with manageable data. Aim for 24-team leagues, utilizing online resources for player data, and prioritize playable ratings over perfect historical accuracy. This approach balances enjoyment with minimal workload, leaving less urgent eras for future projects.
