I mentioned this in the Epic Trial thread, but the most fascinating thing here is that Inside and Celeste- arguably the 2 most critically acclaimed games that were offered in this window- were the biggest "failures" of the program. It's clear that Epic treats the free games as a way to get new Epic Accounts, as they provide not just the number of new accounts, but the "cost" of each new account and the percentage that was new. Fez and Inside ended up having very few people create accounts to claim the games, leading to the stat of $11 and $12 "cost" of each new account created, both of which are close to double the other most "expensive" games. It seems like people interested in Inside and Celeste were already established players
Also, I know that because it was part of a Doxing that it's not the most kosher thing in the world to discuss, but I know that the contract for Fez to appear on Playstation Plus a few years after it's release was part of that, I wonder what the price Sony paid was vs what Epic paid years later for the same game
