I am no longer allowed to give prisoners to the cannibal.

Or give NPCs to the cannibal.

Or encourage the cannibal in any way shape or form.

Or argue about the difference between encouragement and feeding.

I am no longer allowed to turn a teammate in for the bounty on their head knowing full well that they'll just break out in five minutes anyways, even if I'm splitting the bounty with said teammate.

I am no longer allowed to use Sleep as an anti-air weapon.

So you're no longer allowed to be smart? That sounds like a gm who can't design encounters worth crap.

how about daze?

Oh no, he allows non-lateral thinking. I just feel dirty for using at-will sleep to cheap our way out of a fight like that. XD

I am not allowed to use my pick lock skill with my explosives skill just because its cooler that way.

I had a character that was a master locksmith but most of the time I just put explosives inside the lock. ^_^

A gm back in the day banned the used of "Animate Object" being cast on "Blade Barrier", and us using it to walk forward through the dungeon.

Any round that begins with me saying, "Can I borrow every d20 at the table real quick?" is automatically vetoed. Twice if it's still not enough.

Though if it's D6s, and we are playing Shadowrun, this is standard operating procedure.
