OpenFeint — the service that used to ask you if you didn’t like fun if you ignored it — is closing its doors and discontinuing service as of December 14. The cross-platform game platform that allows you to chart scores on leaderboards, achievements and compete against friends is being shut down by owners Gree. At the same time, Gree is hoping that developers who utilized OpenFeint will transfer over to their own platform instead.
As of shutdown “all OpenFeint network calls will be non-functional.” In simple terms, it will cease to work. The actual end date may end up being later than December 14 but developers are urged to prepare for this date. All game information stored will be lost, and should developers wish to retain it migration to the Gree platform ahead of December 14 is advised.
