Heads up that they've run out of Steam keys for a lot of these, and who knows if they'll get more in stock.
Regardless, it's cheap and a good cause, and it's mostly PnP & digital tabletop RPGs/games, so most of the "good stuff" in this bundle wouldn't have a Steam key anyway.
Easy buy, if you don't need to worry about 10 USD in your budget.
