It's not Steam, but on Ubisoft you can get the full version of The Division 2 (with Warlords of NY expansion) for $18, and Ghost Recon: Breakpoint for $15.
TD2 was pretty fun, if only to explore DC. Breakpoint was a huge disappointment for so many reasons, but for $15 it's probably not bad if you want to just have an open world shooter game.
