u/JTostitos is right though that Game Center was designed for this although it has gone out of style with many game studios lately. But it all depends on how the game is designed... If you require constant client-server communications then implementing Game Center doesn't really make sense when you can easily roll your own leaderboard on the server. Source: almost 2 years ago
I got the Music and audio from OpenGameArt.org. If you're interested in using any of it yourself, check out the credits document in my GitHub repository. I have the assets I use linked in there. - Source: dev.to / 9 days ago

Ive looked on itch.io, gamedevmarket.net, opengameart.org, and r/gameassets but didnt find any. Surely bank robberies are a common enough theme to be some out there somewhere, but I cant find them and I just started so I don't know where else to look tbh. Im also a broke college student so it needs to be a free asset or I cannot afford it lol. Source: 5 months ago
I'm a fan of https://opengameart.org/ for RPG assets; just be sure to check the licenses if you plan to release the game. Source: 7 months ago
You might need to dig around a little for animated sprite sheets, but there are plenty of good quality free 2d assets: https://www.kenney.nl/assets https://itch.io/game-assets/free https://opengameart.org/. - Source: Hacker News / 8 months ago
