This is not a game mode as it is a scoring mode. But I hope they bring back the old Halo 2 "Round Scoring". You can do rounds in Halo 3 but it's not round scoring. The winner is only determined by kills in Halo 3. We had a game variant that was a lot of fun where the player only had 3 lives, and you need five kills to win the round, or be the last man standing. The first to win X number of rounds won the match. So even if a player racked up 10 kills in the first two rounds, no lead was safe since it only counted as 2 round wins. This equalized the game a little, plus the halo 3 situation created a scenario where someone could get such a kill lead that it would be impossible mathematically to catch them. Please bring round scoring back.
