So I want to do an online game. I've done some stand alone games for pc, just small hobby stuff on my own, so nothing super impressive, but I want to do a spaceship game online. Basically I want a few people to be able to play at the same time, I want everything done on the server, so there is no need to install client side software. What language should I use, and what classes are used for connecting people to a server like that?
