I have 2 best moments when playing the Halo series, here is one: My friend and I were the only ones that did not give up to fight a premade team of pros who made everyone else quit. Their formation: 2 spectres with snipers, 2 banshees, and 2 wraith tanks. Despite it being 50-12 at end game (8 to 2), we gave them one hell of a fight. Party games like Mario Party have reign supreme in these moments of joy or curses, but Bungie was the first that did it with the FPS genre.
