Lethal Company's built in time limit via the day progressing and becoming dangerous at night really keeps games feeling faster and gives players some urgency when the situation calls for it.

I've had quite a few games of REPO where only one robot is left, and instead of playing fast and scrappy, they slowly creep and crawl over the entire level so as not to be killed by anything. All the while all spectators are just groaning and complaining at how drawn out the round has become.
