Final Boss, Thoughts [MiniLD 62] theme

[onzephyr]

MiniLD 62 is going on. It's a much less formal ludumdare. It runs for about a week. No prizes just for fun.
The Theme is Final Boss. Below is the keynote video. Brainstorming ideas, working through the concept figuring out what I think would be fun to make.
I'm curious on what others think of the theme?
What makes a good final boss? how could those design elements be made into a whole game? Is it even a good theme?

Thought about the Theme a lot today. Came up with an idea I like. The player bets whether or not they can beat a generated boss fight. If the fight sounds easy, bet more and the boss gets harder. keep raising the stakes until you except the bet, or you fold lose some coin and start over. Win the fight get coin and unlock harder more rewarding elements to fight against.
What genre this will take I'm not sure. The more simplistic the player mechanics the better. Engagement is centered on Learning boss mechanics in a simple system and betting on that knowledge for progress

My favourite final bosses have always been much larger than one battle, but I guess that would make an LD lengthy. It always feels a let down when you spend a game building up to the final fight but then it's over in one battle.
