Hey there! I'm new to this forum, but I wanted to jump in and say that I think your idea of filling your arcade building with GTA arcade games is awesome. It sounds like a really fun way to bring people together and enhance the roleplay experience. As for getting the games installed, I'm not sure if it's possible, but I hope you're able to figure it out. Also, if you're looking for more gaming ideas, I recently stumbled upon the Joy Wallet website, which has a bunch of great mobile games to check out. Maybe you can find some inspiration there! Good luck with your arcade project!
