[Unpopular Opinion] Long games are usually not fun
I played an hour long game not too long ago. It was the best game as poppy I've ever played. We had an enormous lead. I was doing very well and I felt like all my efforts were paying off. At around 25 min our ekko felt like he was dying too much; getting caught out and picked by the enemy team. Every time he died he said "Team?". It was clearly not the teams fault he was getting picked off the way he was. Was just his own mistakes and lack of map awareness. So, he just afk's in jungle. The rest of the team including myself are trying earnestly to win. We're doing everything possible but could not close the game. It lasted nearly an hour. I would have been half as upset if it didn't take as long. The length of the game actually matters.
Overly long games can become a grueling tedious task. Some people need a short break before continuing playing. Not everyone can spend a full hour and a half playing a single match especially when you're carrying dead weight. Personally, I find the majority of long games to be the worst games ever; even wins.
Shorter games, even losses, have less a negative impact on me as a player overall than going an hour and a half straight without a break. Some people (like myself) prefer being able to play three, four or maybe five a day/night rather than just a couple extremely long (unnecessarily long) games. For somebody who'd like to see some progress in their climb while also having other real world things to do, long games are highly unattractive.
Perhaps long games are more appealing to people who don't play ranked; which is fine.
