- Server can handle multiple clients simultaneously. - Client can see other players in the game. - Server broadcasts the game state to all clients. - Client receives the game state and renders the other players. - Server assigns a unique ID to each player. - Client receives its player ID form the server. - Server handles client disconnections.. Kinda... Server is ignoring SIGPIPE signal. - Server and client signals are non-blocking. - Moved player objects off the stack and onto the heap.
