I've been buying game bundles since 2016 and I keep an ongoing list of of duplicates that I have ZERO need for:
Google Spreadsheet [docs.google.com]

I have details of when and where I bought them and kept a record of how much they go for retail before any Steam sales (just to better help us both see if a proposed trade is fair!) I'm not too much of a stickler on this, but if you want XCOM 2 I would hope for something worth more than $0.99

All my keys are stored in a text file so PM is the only way to get them. I rely heavily on the honor's system when we agree on a trade. I will PM my key first as a sign of good faith (as long as I don't get sketchy vibes from your account) once you've confirmed the key (I may have a few broken ones as I've had them for awhile so I will not ask for a key until I see your account with the newly redeemed game!) THEN at that point I'll be expecting the key from you. I hope this sounds reasonable and fair!

In terms of game trades, it would be easier to say what I DON'T want as I just like padding out my library with games that I hope to get to one day!

- I don't want games already in my Steam account (this one is obvious but you never know if someone forgets to check!)

- I don't want any X-rated or visual novel games (I don't care for those)

- I prefer no strictly sports games (racing games are an exception, and themed sports stuff. Just not like your run-of-the mill NBA or Pro Golf stuff)

Beyond that, if you got a game that you want to get rid of and I don't have it, I will absolutely consider it because I just want to see these keys find a home outside of my spreadsheet and I want more games in my library because seeing numbers grow brings me great joy!

Looking forward to making some good deals and helping find homes for the keys I neglect in a Spreadsheet!

I'll do more with this box once I have an idea for one 😅
