I brought over my Nintendo Switch for my nephews to enjoy during the family Christmas party. The family game room got flooded due to a septic tank problem so it was out of commission. Luckily the Nintendo Switch can be played portable as its in truth, a tablet. I only brought over Super Smash Bros. Ultimate so the boys wouldn't be trying to play a million games at once.
After learning the rules and getting used to it they had a blast with it. After about two hours, I let them play each other alone for the most part. They played it for about another hour and a half until the battery died.
