If you have never played on a PC, and your multiplayer experience has only been delivered to you
via matchmaking, then you will never really understand. But try to imagine a host hosting a game
while never turning his console off, and you can always reach that room and play there whenever
you want, night or day, because its always on. Now imagine that host has a Pentagon grade
internet connection and his X360 can handle 64 players in that room. On top of that, the guy whos
the host is actually resurrected Ghandi, so you will all be treated with respect, anyone using
racial slurs, being offensive or just detrimental to gameplay experience via TKing or exploiting
glitches, is going to be removed from that server forever.
Now imagine dozens and dozens of custom maps running on that server, which you will get for free,
because IWs not making them. Then imagine entire communities and forums built around that one
room (server). You recognize people who visit that same room, you befriend them, you have fun
with these familiar folks.
The story goes on, and thats what were missing. All of it is gone.
