This thread on RPG.net is a very humorous (and non-mathematical) approach to comparing a lifting action across systems.
Aberrant: Of course you can lift the rock, and everyone is in awe and/or terrified of you for now. Ultimately, it won't matter because all your works will be undone and you can't have children.
Mind's Eye Theater Vampire: You bid a strength trait and play RPS, then get distracted when your ex walks by, and gossip and complain about the other players behind their backs until the session ends and everyone gets drunk.
