This list was compiled based on years of experience along with hundreds of games with a focus on competitive victory, and based on all expansions being present, playing with the default ending. (I know many of you have been playing Talisman before I was even born, I'm not claiming OG) I'll post my reasoning for setting it up as such sometime in the near future. But if you have any specific questions concerning the list as a whole, or any character specifically let me know!

Honestly I don't think my final rendition of the list will look exactly like this, as my opinion of characters change almost every game, as new things always happen. But generally I think this what the list will look like.
