Don't be too strict or too lax. You don't want a RP to go fully off the rails, but you also want to keep your players from rioting because you're forcefully railroading them through the plot. Players are distracted by someone? Tie them into the plot somehow--perhaps they've been sent to assassinate the players or something like that.

Make sure to read sheets so your players can't try to pass something vague as part of their sheet. I'm normally not picky on this, but if people say they're strong, it's still hard to imagine them lifting a bus without superpowers. None of that "but the sheet says they're strong!"

Thank you :)

Okay so I have to be pretty flexible right? But I also have to sometimes force things onto the players at times? By the way, if there's some sort of clear ending to this, should I be flexible about that too and instead base the ending on the player's choices? Or would this be too complicated?

Thanks a lot! Your advice is hella useful. You mentioned taking you time with it. How long should I spend lore building? Or should I build lore along the way?
