What your talking about is cluster based networking. yes that was my plan :D. there is interest of course. If you want to do it. Please go ahead. This would save Velotjet and me great time for some one else to handle it :)
I was starting to do the PoC Here.
But then I was faced with 2 problems.
1. Photon doesn't have Channels or Routes. They only have from what I can tell are isolated lobbies. So i couldn't sit cluster server to be the game logic for mutliple rooms :(
2. I would have needed to install Visual Studio Express. We all have our bias for coding langauges. I won't work with .NET unless I'm paid. I'm not being paid. I won't touch it. :D
instead if no one set's up a C2 cluster network. I plan to use NodeJS Tycho or ActionHero. Which both can be configured for cluster networking :)
My question is. Would people pay a descent amount of money on Kickstart for a team to get this going. Or pay an X amount for a plugin. I would love to quit my job :D
Yes, You could do DDtank like game. However, that game looks like it will have a lot of server based code. So it's going to be a lot of work and at this moment. Your going to need to learn a programming language... unlsess of course some one get's a cluster network going :)
I don't know. This wave of "is there online multiplayer" questions has a different feel to it.
