The Houthi rebels are attacking peaceful vessels that have nothing to do with this conflict. I personally fully support securing these shipping lanes.
If Iran didnt support the Houthis i would support them helpibg aswell. But still, there is such a thing as Freedom of navigation, so the iranian ship can go there. They just can’t provoke a conflict.
You’d be correct about tf2.
I would define a hero shooter as having Moba style characters in a Counter Strike style environment.
