I would do karaoke in a heartbeat! Good stuff, MP.
In the Hero System (used in RPGs like the superhero game Champions), character abilities, weapons, equipment and the like are constructed from points, with the base ability costing a certain amount based upon its relative power. That cost is then modified with advantages and limitations that either increase the cost (by making it more useful) or decrease it (by reduing its utility).
For example, here is a Hand-to-Hand (of HTH) attack that you probably don’t want to bother with.
(Anime: Azaumanga Daioh)
And sometimes you can build things that seem absurd at first glance. Like:
(Anime: 2x2 Shinobuden aka Ninja Nonsense)
Glad to have you back MP! What’ve you been up to?
Note the no crusts, lol.
