If I only need the leadboard feature and thus I do not want to add any achievements in the games, is there anyway to do this? Currently I can see that at least 5 achievements are required before publishing in the developer console.
I know that adding 5 dummy achievements can work, but I am wondering if there are any settings on this that I missed.
Thank you very much for help/clarification!
Nope, you have missed nothing. Dummy achievements will work fine to allow you to publish.
Also, you can set them all to hidden so they won't show up at all.
