With fighting games is that I feel like it requires a good deal of knowledge about the specific game to understand why what you're seeing is impressive.
I think RTS his the sweet spot where it's generally pretty apparent what's going on and who's winning and losing when armies fight. But also the scale of the game can be apparent as well and you can see that the impressiveness that one person is controlling workers and buildings and upgrades and making small adjustments to the army positioning, etc.
