This game is famous for it's fast engine, and great online multi-player gameplay. Also very user-friendly, very editable, and theres many great modifications that have been released by Quake players that make this game much more entertaining. Pick it up today, it's best to order it off Amazon though, it's impossible to find in stores these days since it's a little old.
