LordCom - I program for a living and have been for some 25 years now.... and I have many unfinished wrecks in my past...
I built an online "Mall" for general use or for companies to automate reordering supplies etc... Just as I was ready to make my move with the finished product - this little thing called the internet was becoming available for dialup... UGH!!
In short - to answer your question? My opinion is:
If YOU make a FAST, Easy to use means for people to make their games multiplayer - and ITS SCALABLE (enough where you can have a few servers running the whole thing together) and it has good performance - people will try it - people may buy it... never enough people buy anything unless you have the marketing power of yahoo, google, or of course Microsoft.
I I could RIGHT NOW - Download your app - maybe a limited trial - (1 server, two clients) for testing, enough help docs to quickly get packets going smoothly ... say a chat, and some floats and integers, and I could choose between UDP and TCP/IP or use both....
I PERSONALLY would go for it - and if I liked it - I MAY buy it.
But unfortunatly - You need to take the risk and build it and see - or move on to something you know will be more readily "liked"... perhaps a bigger market for the idea etc.
Getting opinions is cool - but this is a niche market - how many people on the street make video games? Most just play them, the rest just don't understand how we can play them as long as we do
So - MY OPINION? If its fast and easy to use - and I can implement it easily with my DarkBasic Stuff? Yeah - I'm interested... If its a pain in the butt? I'll make my own - just for the game in question - just enough to get by... then if I make a million selling the game - I'll rewrite/modify my network play with cool features cited above
Good Luck Lordcom! I hope you CAN make something we can use soon!
(I needed that functionality yesterday! ...for the game I'm not finished with yet hahah
