Hello reynoldlariza...
Ok... I´v entered on those sites and I saw what those tools can do...
Some screenshoots are very good!
But... lets start doing some thing?

I have my idea, a 3d online game with a lot of users walking and fighting in a big or maybe infinite terrain!
I can do the chars and the 3d terrain, the textures and maybe some light effects.

But, to create a online game, we need a server.
My opinion is:
We can use a free mysql server to save the users ip
And all user that login in the game can see the other users.
To do this, we have to know how use the "winsock api", to communicate user to user
and "mysql c++ api" to select the ips registered in the server.

you got it?
I dont have a good experience with winsock, just some tutorials but I never did a real program.

I know that use a free mysql server can turn the login process very slow
but I don't know other way to save the users ip´s on the internet!

You know some thing like that?

My friend draw this:


Good no? he I´ll put this char walking.
