Issue is that many people have different standards and quality. Seen it all from lazy people to people that will metagame to make their character seem superior, and even people make a character sheet only to play a character with a completely different personality and agenda.

You wouldn't see it much in a 1x1, but in a group RP these traits can become infectious with people subtly adjusting their writing to counter play so that they don't get metagamed or power played out.

As for how I view 1x1s. I try to keep them the same as a group RP, but it's harder as I feel you're acting as both gm and player. Surprise moments don't always work out, and I have seen 1x1s where someone created an npc and the other player kill off that npc with their character, so communication is key in order to prevent this. :\

This right here. So true.

Also, on the note of mystery; I had a friend that had intended for part of his RP (not sure if it was meant to be the whole thing) to be a mystery. Like, a plot involving a kidnapping or something, can't remember too well. But what happened was one of the players suddenly invented a convenient note left by the bad guys that claimed the kidnapped people were tied to the railway tracks or something (I think it may have been a Western RP?). The rest of the group just goes along with this and bam, whole mystery plot ruined because one guy decided to pierce the metagaming heavens. And because the rest of the group had played along, they wanted to keep going with it in spite of my friend's protests. He basically just left it to die after that.
