UsernameTaken2: Going through all my receipts and adding it all up would take far too much effort, so here's a bit of JavaScript that will do it for you:
Thanks. For me it took more like a minute to run.
It said "15198.49" which I presume means I've used about 15200 euros on GOG.
That sounds plausible, I guess. And no I don't really feel bad about it, I've been here now 12 years and my electric car which I bought two years ago cost twice that. Or, last summer when we went to Thailand for four weeks, I think we spent something like 5000 euros on that one trip alone (we didn't spend time in expensive hotels or anything, quite a lot of that money went to flight tickets alone, for four persons).
Money is meant to be spent, I can't take my money to the grave with me when I die, but I can take my GOG games and my electric car there, and keep utilizing them in the afterlife if I get bored or something.
