What should I do first?

Sandr0G

Should I finish the game first and then implement Photon, or should I implement photon from the beginning of the development?
Thanks.

It's up to how you work best, actually.
It makes sense to get a grip on networking before you implement that, so starting early might be good. On the other hand, if you start learning networking while you implement your game, you might do end up with a not so great networking.

In best case, make a game, then make a multiplayer test game and then develop what you wanted to do in the first place.
