Pretty much what the title says. If you were ever able to play a character with these following intelligence scores, what would be typically expected?
Int Score 5
Int Score 10
Int Score 20
Int Score 30
Int Score 50
Int Score 100 (lol)
Int Score 1000 (yeah, ur head would probably explode....alot)
Int Score 10000 (omnipotent?)
As presented in AD&D, an int of 3 is an animal. Between 3 and 8 is retarded. An 8 is stupid.
10 is average intelligence.
18 is Einstein (or any genius level intellect).
20 is super genius, we're talking Kim Ung-yong or Gary Kasparov.
From here on, it is purely conjecture.
Beyond 20, no one yet born has ever been that smart. A 30 would call Kim Ung-yong a simpleton, and on the reverse, Kim wouldn't even be able to comprehend his level of intelligence.
A 50 would be comparing an mentally retarded infant (Kim Ung-yong, in this example) to a man twice as smart as Einstein.
What they would act like is entirely different altogether. Purportedly one of the most intelligent men alive, Chris Langan is a bouncer, and a bit of an oafish one at that.
To create a Gundam, comparing it to current levels of technology, a 25 would more than suffice. The Death Star would be much more reasonable, probably only a 20.
I won't touch the infinite laser cannon with a 10 foot pole, though.
