I could do North, but I'd rather keep to Worldsmith for now. How about you go to https://lestrades.com/@Nao/ (I'm the site admin), and check out my tradables? Maybe you'll find stuff you want there. You can match them against your wishlist, make sure to import it by logging in with Steam. I have hundreds of Steam keys-- here on Groupees I can only trade my itch keys, and I can't do complex & multiple offers. So frustrating :-/ (I also have itch games I haven't put up for trade here yet. Too lazy because I usually never use that trading system.)

(BTW, I didn't even know you could leave messages on profiles, lol.)

Cool! I'm looking around and will get back to you. Is there a particular procedure for inter-site trades? Do people just exchange codes in messages?

Yes, you can send by PM on the site, or add the person to Steam of course. It's all pretty laid back-- the community is experienced and there have been no scammers so far (fingers crossed). Just trade with people with a few trades completed on their profile! Also, I added a few of your wishlisted games to my tradables. I'll add North as well but it's the itch version, not Steam. (Lestrade's doesn't support itch yet. It'll come eventually when I add the ability to add any itch games to the database.)
