There are soooo many but I was watching a particular one tonight, now in fact and the consideration hit me...a very cool setting.
Wall-E
Now as with any movie, some measure of modification is in order to make it all work IMO. For Wall-E I would have the recycling bots harvesting, inventorying, and stacking the raw materials as well as the odd bot with a glitch that collects a certain thing...soda cans, keys, doll heads, etc.
As for the people left behind...I would have few.
Certainly a small people, 1' tall for example would be welcome...less resources (ok in a science fantasy game less, in real life the small one would use much more relative to size...but we are accepting spider goats so we move on )...harder to see and thus safer...etc.
Mutant plants would be high on my list...Mother Nature putting her foot down, vast areas of green (purple, orange, etc.)
A counter to the people...a classic mutant rats...vast empire of ratness.
Certainly the other common animals...cats, dogs, etc.
But I am seeing the small people being a focus point for this thought...maybe a large one being born every now and then, 2'.
Then all the bots...lots of bots...searching, recording, working, etc...
And the great ship...I would have it in lazy orbit...for many generations...the ship being a perfect lap of luxury and the people being fat and lazy...or...damaged and ruined with lots of problems...or...a little of both.
It comes back.
Sounds like great fun to me...it cuts down on the wide range of complete wackiness but full of color and potential.
Thoughts?
