[H] Serious Sam 2 / Double D / HD: First Encounter / Random Encounter ; Shank ; Shank 2 [W] Offers

Because I am not allowed to sell my age 18+ games on ebay, I'm offering them here for trade:

[Have]

• Serious Sam 2
• Serious Sam Double D
• Serious Sam HD: The First Encounter
• Serious Sam: The Random Encounter
• Shank
• Shank 2

Note: These are all Steam keys, because Steam won't let me add them as gifts to my inventory.
I know there is no verifiable reason to trust me, except for the status of my steamgifts.com account and my Steam account, so I let you choose the way to trade - which ever you prefer.

[Want]

• Make me an offer, that you think is fair.

Note: I am absolutely NOT interested in any kind of puzzle games and tower defense or MOBA style games!
