I think this ending has a lot similarities with the MMO SWTOR's KOTET xpc ending. The throne and a massive fleet, the fight with Valkorion/Palpatine was also quite similar. Even KOTET was handled better because we had enough interaction with Valkorion before.
Also the last strike, if you are Force class, you also use the lightsaber to strike and reflect Valkorion's lightning.
