Fine for a while but eventually it loses its appeal. Also, games like this tend to end up taking themselves far too seriously; to the point where laughter and entertainment are frowned upon and everything has to be high drama. No thanks. <snip> I'd rather play in a game where I can be entertained, be entertaining in return, and share some laughs along the way.
On the former point: your experience differs from mine. I'm playing in a game in which the PCs are playing for high stakes. No PC deaths so far. We've managed to save some NPCs from horrible deaths, but not all. And then, when the PCs are returning from a mission, we play out campfire conversations, and so forth, in which the PCs razz each other, playfully... which IMO is all the more fun, because they're blowing off steam from something important. We've had a session which spent substantial time on what happens when the team's Barbarian tries a double shot of super-enhanced liquor. He had a good trip, and the rest of us kept him from doing too much damage, at worst he would have trashed the bar or fallen into the latrine, TPK was not on the table for that scene, a game can include both high-stakes scenes and low-stakes scenes.
We had also had a scene in which the PCs were in a high-stakes combat, and the sorceror cast Enlarge on the dragonborn paladin, so the players made kaiju jokes. The PC had an experience which caused post-mission nightmares (the PC woke up screaming for several nights afterwards.) Players are making kaiju jokes, and then puns riffing on those jokes. These can happen in parallel. Mood at the table != mood in the story.
If you say there are any gamers anywhere, who DON'T want "entertained, be entertaining in return, and share some laughs along the way" - well, if you've met them, then I cannot contradict your experience; but so far as I can tell, we ALL want that. We just vary, in how to accomplish it.
