Well you are in luck I have made 8 video games that are totally free and open source with 1 non open source and paid expansion for one of the games, link to those games and paid expansion here: https://daniel-hanrahan-tools-and-games.github.io/ , do you think 100% free and open source games are the solution to this parts shortage and what other solutions do you might have to the RAM shortage?, no wrong answers. Game links start from Bowling Mega Mix to and end at guide the marble, paid expansions are in each of those links, I thought I would let you know where those related links would be.
