Can we just focus on the thread now, please? Everything is fine, that's only my feelings, not yours.
We should do some research:
https://en.wikipedia.org/wiki/Uranium
We should consider some aspects of this material and answer about few questions:
- is it flammable? what objects and forces should make it burn? what damage can it cause while burning?
- is it is it explosive? what objects and forces should make it explode? what damage can it cause while exploding?
- is it radioactive? how long should be radius of the radiation? what objects should get damage of it?
- is it heavy? how much and what objects can carry it?
- how humans and/or aliens can use it?
I think there's really necessity to make a table with all similar objects and informations about how they should work as default. Especially when we'll porting objects logic outside the game's engine. Then there could be mods/levels with for example different damage parameters etc.
