I've received several messages about offers with free or given away games. For example, The Desolate Hope, which is free on Steam, and the recent Indiegala giveaway of Bloop, where anyone that wanted a copy could get one.
Should these game be against the rules and banned from offers? I don't think they should. While the trade value is obviously much lower a big give away and next to nothing for a free game, that shouldn't disqualify a game from the site. It's up to the accepting side of an offer to decide. Should the offering side disclose that the game was given away or is now free? That would be polite, but I don't think there's an obligation to notify. I think this is a responsibility of the site.
Like the previous Decommissioned games thread, I'll go through given away tags and post them here. Unlike decommissioned games, where it's easy to verify by going to the store page, "given away" isn't as easy to verify nor is there a clear threshold (should a giveaway of 100 games be flagged?).
The goal is to display this information on the offer page so that the information is disclosed to both sides. I'd like to hear any suggestions. Also, anyone can post games that were given away or switched to free below.
