How much are you asking for both Just Cause Collection and Far Cry Franchise Pack? Check here if you see anything interesting, I've also got keys, but just tf2. I can change them for cs:go keys though if you'd rather have those. Feel free to add me if you want to discuss!
Just cause collection comes with just cause 1 and 2 with all dlcs. And Farcry pack comes with farcry 1-3 with all dlcs
