I only have a backlog because I kept accumulating games from Humble Bundles almost 10 years ago because I kept telling myself that I would eventually build a good PC, and I would even buy a couple of games I couldn't run back then in my laptop, such as MGR Revengeance or Dark Souls PtDE. For context, I have games and series such as:

>Batman Arkham Asylum and City GOTY Edition
>Commandos series
>Deus Ex series
>F.E.A.R. series
>Hitman series
>Civilization III and IV
>S.T.A.L.K.E.R.

I have 159 untouched games in my Steam account, including like 10 new ones I bought this summer because I finally got a PC, so instead of playing everything that I accumulated, I'm now stuck playing Halo MCC. At least I finally beat Revengeance, but I already played Dark Souls on Switch, so PtDE will remain forever untouched.
