Close to $162, at least as far as my account history goes, but that's over a few years, and I have 48 games. I wait until the huge winter sales event and splurge whatever I get for Christmas on a few new games. Never thought I'd end up with 52 hours on WolfQuest of all things, and that's the one game I didn't get on a huge discount.
Probably about ?50 maximum, including other stores that just give you steam keys.
Most of my 200-300+ games are either crap from humblebundle that came with "that one game I actually want" or gifts. I've bought like 5 games on Steam, and it's pretty much just the Valve ones...Which I would have gotten on sale for next to nothing.
i've been on steam for almost 14 years and i've amassed 873 games, so probably way too much. a lot of those are trash from bundles i'll never play though, but i've still spent a good deal of money
Oh gosh, and you have over 1,685+ games on your library. I wonder how big your scroll is on your steam library.
Also, don't forget to add all the subscription payments from FFXIV.
And.... I'm afraid to check mine. lol I want to live my life knowing I didn't spend more than a thousand on my steam account.
