Lol no, not even gonna try.
Like I said, a lot of them are from bundles, and when you buy a bundle for 1 or 2 games and get like 6 others it adds up.
Essentially I have certain purchase tiers:
Is it a day 1/full price purchase? Definitely gonna play it the moment I'll buy it.
Sale purchases I also priorize, but a few super cheap ones may or may not fall through the cracks occasionally (aka I only get around to them months later).
With bundles I'm fine as long as play one or 2 shortly after buying the bundle. Others I might get to months (or sometimes years) later, others never, but I don't mind as long as I "got my money's worth" out of some of the games.
Essentially my rule of thumb is the more I'm willing to pay for a game, the more I also focus on playing them.
I've made peace with the fact that I'm buying more games than I play and I don't really mind as long as my spending is within "reasonable" bounds.
I do play quite a bunch of them though, like this year I'm closing in on 70 completed games (a lot more than the previous ones, but I also have been playing way more short games than long ones so it's expected. Also those aren't all games I bought this year).
Ah I see. Damn, I was thinking "this guy has two PCs, side by side, playing two different accounts at the same time." Still 70 is incredible. I haven't counted, but I'm probably at like 10 on the year. But I tend to get lost. Like I started playing Prey again, loved the level design and thought I'd get Metroid Prime going. This lead to Super Metroid. Then got busy with the summer and didn't play anything for a month and forgot what I was doing. It's like game dementia.
So yeah, hence my short leash on buying.
