A bit of competition is great craic, right up until somebody starts acting like they are in the final lap of a world championship. The sweet spot is simple: pick an activity that brings a challenge, adds a clock, and still leaves everyone laughing at the end.
That is why timed activities work so well for groups of friends. You get the buzz of trying to beat each other, but the format stays light. It is less about smashing into opponents and more about who can keep calm, stay sharp, and maybe avoid talking too much before their turn.
