Q: If I scientifically explain why I should have and ability, will I get it? For example, lets say I can heat up my hands to several thousand degrees Celsius, in reality, I could turn the air into a plasma, would I be able to do this in gamma world?
A: Yes and no. Outside of combat, I would allow a lot of rule bending and logical arguments for doing stuff because it can be easily added into the rules. However, in combat one could become absurdly unbalanced, so no. As for an explanation why in game, sometimes physics and logic don't work right in Gamma World. Or maybe you're too focused on fighting to take advantage of it.
Tldr: Out of combat: yes; in combat: no.
Q: If we do something difficult do we get a piont to the stat that it involved? For example, if i remember some small, obscure fact from 3 games ago that really helps us now, will I get an extra wisdom point?
A: No, but if it is a "skill encounter" you will get experience for it. Normal game skill checks earn you nothing.
