Mario Kart
Nintendo's racing series known for its item-based party gameplay.
Where Mario Kart comes up1 episode or test
Mario Kart uses a negative feedback loop: leaders get weak items like green shells and banana peels, while trailing players get the bullet bill, golden mushroom and blue shell. That keeps races close and dramatic. Mario Kart 8 added the super horn, which destroys blue shells. The lesson: use comeback mechanics in party games, and give leaders a counter to the most frustrating one.

From Game design note on feedback loops
What was said about Mario Kart
1Mario Kart's item system as a negative feedback loop
Mario Kart hands weak items to leaders and strong items to players behind. Leaders get weak items like green shells and banana peels. Players at the back get the bullet bill, the golden mushroom and the blue shell. Winners are punished and losers are rewarded, which keeps everyone in the race.
This creates an ebb and flow of turnarounds and drama, which suits a party game. The source frames it as a negative loop that counteracts change and keeps the system in equilibrium.
Mario Kart 8 gave leaders a counter to the blue shell. The blue shell is the most hated part of the balancing loop. Mario Kart 8 added a super horn that can destroy blue shells, so the race still balances but the leader has a response.
The source says the super horn "does give you an effective strategy for destroying blue shells". The loop itself stays in place.
Treat feedback loops as outcomes that change the odds of later outcomes. A feedback loop feeds a system's output back in as input, so a player's success or failure changes the likelihood of later success or failure. Mario Kart items are the negative-loop example.
Positive loops reinforce winners and compound failures, as with Call of Duty kill streaks and losing a piece in chess. Negative loops counteract change and keep things in equilibrium.
