AFAICT SKG doesn't really make a distinction between games bought with a one-time purchase and games that are subscribed to. In their FAQ, they explicitly say it would apply to MMOs too (see https://www.stopkillinggames.com/faq "What about large-scale MMORPGs? Isn't it impossible for customers to run those when servers are shut down?) although they don't spell out whether they mean exclusively games bought with a one-time fee or games that are subscription-only.

Ross from Accursed Farms said this in a video FAQ on youtube:

" Would this initiative affect subscription games? Well, that's another question that depends on what the EU says. Personally, I think it's very unlikely because that doesn't fit well with other existing consumer laws. I think the only way you could even make that argument would be that this is necessary for preservation and most governments don't seem to care about that at all. However, I don't think this is a huge loss, since only a handful of games operate that way today. So if we can give up those but then save 99% of other games, I'm willing to make that bargain. "

so it seems like they actually are suggesting that they'd like for (a law that came out of) SKG to apply to subscription games but there's an understanding that it probably won't.
