Exophase VS Game Center

Yeah, the best sites I've seen that actually have leaderboards with rarity points assigned to the trophies are psntrophyleaders.com and exophase.com. Both great if you have a leaderboard itch but don't want to play shovelware. Source: about 1 year ago

As the subject says... If you want to archive your achievements and total time played as well as per game hurry up and head over to exophase.com and sign up for a free account. The owner of the site has said he is NOT wiping the data and it will stay on your profile post Stadia's death. Source: over 1 year ago

For all you Stadians who like to track achievements, you can sync your Stadia achievements over at https://exophase.com before Stadia goes away and keep them tracked next to achievements on other platforms. Source: over 1 year ago

If you like stats, you might get a kick out of exophase.com. Source: over 1 year ago

But, fear not! There is another service out there, exophase.com, that lets you keep track of your achievements across ALL different platforms – including Stadia! Here is a capture of my profile:. Source: over 1 year ago

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
