Are there any current good solutions for integrating api's like leaderboards and achievements into your game? For example, I'm working on cross-platform games and using google play and game center for achievements and leaderboards, and a lot of my gameplay is centered around competing on the leaderboards. I want a replacement for when those services aren't available. (Mainly web hosting)
I'm not that interested in a local leader-board, and I know scirra arcade has a leaderboard, but I'm looking for something that works essentially anywhere, regardless of hosting location. We used to have exactly this with the clay.io plugin but that has since been discontinued.
