I think the environmental problem should be approached like a budget - figure out how much we can spend, and than allocate it accordingly. We have to avoid being 'penny wise and pound foolish' with the environment. If I look at my own environmental footprint, the biggest changes I can make are in my heating, my flying, my driving and I am trying to change those things (working from home, and changing my holiday destinations) Will be looking into isolating my house as well. Gaming does not even register compared to those, as it does for most people.

It will start to matter if it costs ~3KWh's of gaming per day. Probably even more if this is meant for serious gamers, they will game more than 3 hours per day.

It doesn't matter it's genshin impact or animal crossing but it definitely starts to matter when your gaming costs almost two orders of magnitude up in power from the typical case.

3KWh a day is $0.30 or less than $10/month. (in Seattle).
