Kobaltic, that's what I have been trying with no success. It's the reason I posted about this because that process was driving me insane. I think the last attempt was just crashing AppGameKit completely, with a fatal error.
@ Sagetech, I think the problem you have trying to offer a service like this, is the fact you are one person. People think about the long term with things like this. If something happened to you what would happen to the service? If you were laid up in Hospital for 6 weeks, or worse, would it be maintained? These are valid questions. I would be interested myself, but as you say you need a bit of interest from several members to set something like that up, I would think. That's why I suggested TGC partner up with someone, make it official looking, and hopefully sustainable.
@Mt Valentine, if you think you can do it, why not do a tutorial for AppGameKit people can look at? I'm sure a lot of people would be grateful for any help in this area.
I haven't used either open feint or gamecenter so couldn't comment on their qualities or bug bears. If people really do download a game more because it supports one or the other, that seems branding gone crazy. I mean what's more important? Gamecenter support, or a good game? Games should sell based on how good the game is, not what services they use to support the games.
I have been looking at a service called moai, which looks pretty good. However it is based around it's own api for game making, and not really designed for AGK. Although by the sounds you could possibly use it if you know Lua, and their own scripting language. Again this is not something I want to do at present. But it could be worth TGC taking a look themselves.
TGC were asking for ideas to get AppGameKit more accepted by the dev community, this sort of thing would be one of them I think. I got AppGameKit to make making games fairly easy and fast. I don't want to get bogged down in the mire doing an online high score table. I'd much prefer a simple way to integrate something like this
