Just for a bit of fun, Steam now let's you see how much money you've spent:
https://help.steampowered.com/en/accountdata/AccountSpend

I've had my account over 13 years now and apparently I've spent $1,201

I can't tell how long it's been, but I'm standing at some 518 $.

Think I've been a good boy.

1600+

It's Kanum's that'll be scary

erm -- $4,738.39

Still around 100k cheaper than a missus.

$4,829.89........

No comment.

$8,192 hahaha, suck it life savings

$253.31

Yes, I'm a cheapskate with games!

It says $14.73. But that is not right ofcouse. In reality it was around 90$ (on steam). In 8 years. Yes.

If I add all my spendings on PC games from the last 10 years to that, I guess I have spent between 300 - 400€ in total.
Beeing very particular, not easily impressible, never quite satisfied and a grump in general, has it's financial benefits it seems ...
