Falci: I know this sounds like a stupid first world problem, but I'm feeling kind of frustrated, because I want to buy something, but can't justify buying anything right now.
Do you guys ever get this sort of feeling?
Not really... For me it is easier to resist buying games with DRM, logic tells me I should postpone buying them until I actually play them. Hence I haven't yet bought e.g. Skyrim Legendary Edition even though its sale price finally went under 10€, which I considered to be the limit I am ready to pay for it (with DRM). Yet, I still decided to postpone getting it, after all I am still playing Daggerfall. :)
With DRM-free games, I am more likely to buy something to the backlog with no idea when exactly I will play it. I feel it is a safer and more future-proof purchase, so if there is something I consider a good deal, why not?
Yet, even there I don't get the feeling that I just need to buy
something, not that important what. I get the urge to buy something if I see something interesting at an agreeable price.
I'm now playing and enjoying Freespace, which I originally bought in the late 90s or so, and years ago from GOG. The last third mission ongoing now, hard to meet the secondary objective but I enjoy trying greatly.
