I am not sure: did the word doom predate the game or did Id invented it ?. The word origin isn't very clear in wiktionary [1].

This is ridiculous. Companies don't magically own all the words.
Slogan trademarks are definitely another monster in the trademark space.

Huh? Is 'from Old English dōm ("judgement")' not clear enough for you? It's a native word; as far as we know it's infinitely old.
That doesn't mean much. Compare https://www.etymonline.com/word/loot :
> "goods taken from an enemy, etc.,"
> from PIE *roup-tro-, from root *reup- "to snatch"
This would make it a cognate of rape, by the way.
But being traceable to Proto-Indo-European doesn't tell you anything about the age of the English word. That is a loan from Hindi, and only dates back to the British Raj.
