Well the inclusion of live service games certainly changes where I fall in the spectrum, because I'll spend anywhere from 20-70% of my gaming time a week playing multiplayer stuff like PUBG
When it comes to single player games, I'm typically playing things that are usually nearly new but not "brand new"
and that's largely driven by price. I'm perfectly willing to wait for a AAA game to hit $20-30 bucks before buying it. I just don't get to them quickly enough to justify paying full freight.
Launch games are often expensive and retro games are often expensive-ish (or rarely go on sale). But stuff that's like 0.5-4 years old is often heavily marked down and that's my wheelhouse budget wise. E.g. been playing a lot of 2018 releases lately, that's kinda where I am at atm. They feel plenty new to me even when they aren't brand new.
I'll allow myself 1-3 launch purchases a year, so I'd say 80% of what I play SP is "old"
So with that in mind I hedged and put myself in the 40-60% category. in the poll.
