Hey slash good to see you around. Forums been pretty dead this last year. Can't say I have any time at the moment on the dev side but I do have some small tips.

Firstly if you haven't already setup a private git repository and push everything to it. Learn to love git makes everything easier.

Secondly do up a 20 pg design document outlining core features. Be rigourous in following it early on. It's important you stick to an attainable roadmap. Boring core elements are much more important than flashy features. Try to figure out what happens server side early on.

On that note, have you checked out Amazon lumberyard? It's server side stuff is all hosted on aws and scales ultra easily. If you ever need to integrate with a game backedn service it would be a cake walk. In fact have a look at playfab or gamespark, pretty decent services.

Good luck man
