As i said in my 5-Star review (which are private on itch so im reposting here):
Rise of the Apes is a fantastic and evocative system, that creates a game in 3 act.
If you don't want to stop after act 3: the very simple but incredibly flexible Rise and Strength systems could be easily applied to continue the franchise or spin off in your own direction by applying a new set of 3 scene acts in the same manner presented here.
I look forward to the time i can find time to play it!
