Playing #BeyondGoodAndEvil makes me speculate that action-adventures are essentially brew-pots that represent an average of the most popular genres that were being released during their time
BG&E is an average of 3d platforming, stealth and racing, which were popular during the 6th gen
The Last of us was an average of the 7th gen that consisted of third-person shooters, crafting and survival horrors
Either I'm noticing a pattern, or I'm missing the forest for the trees
