Maighstir: Installed but never played?
I have several though that I have installed and only barely touched after that.
For instance, I am just now thinking of installing Fallout (GOG classic version), and some of the recommended mods for it. I already did that all on another PC which I am not using anymore, so now I'd need to redo it all on this PC so that I could finally play Fallout properly. I only played it barely out of the starting cave on that other PC.
Same for Icewind Dale 2, I was still stuck on that other PC creating my party, trying to understand the different aspects of the ADD system in IWD2 (different than in IWD). Mainly I tried to create a similar party that I had earlier in IWD, but ran into some problems understanding how to achieve that, due to the differences.
