For the sake of brevity, I’m just going to agree that I’m sea-lioning.
Now, explain how what I’m doing is unethical.
Do you think it’s unethical because it uses stolen art?
If so, I don’t think there’s an issue because I’m not publishing anything I generate.
Do you think it’s unethical because of the electricity usage?
If so, you could make the argument about any frivilous activity which generates electricity.
I really don’t know of a compelling reason besides these two which raises a red flag for you.
It’s bizarre, there are a ton of mini-games, combat is sometimes fun, storyline is yakuza melo-drama, dripping in themes around loyalty, honor and sacrifice.
It has a little bit of something for everyone.
