Yes, I'm thinking of Java as the game server/connection manager. I guess what I'm looking for is very much network related. Flash is pretty much decided on as the client, as we have excellent Flash talent here, and practically no applet nor Swing talent (I'm a J2EE developer primarily). It's looking like the game will be a trivia game. 5 players at a time in a game, first one to answer correctly gets the points, that type of thing.
So, I'm looking to possibly build our own game server. My original post was to ferrett out any newbie/introductory material that I should look at to get started. Perhaps there's nothing special about game networking that I need to know, and it's just straight networking but with game rules, etc.? I'm also looking at the following products as alternatives, does anyone have any experience with/opinions of them?
