[H]Nightsky andCrayon Physics Deluxe steam keys-Don't Starve chrome store key [W] open to offers

Hi, I think the title says it all.
I've Nightsky and Crayon physics deluxe steam keys
(from humble bundles)

and a Don't Starve chrome store key left.

I don't really want a precise game (I'd like the dragonborn dlc for skyrim, but I don't think it would be a fair trade)
I mostly like rpg, retro games, or something with a multiplayer functionality (online or on a single computer)
Or something with frequent updates (like Don't starve, or Minecraft (not these ones, it was just exemples)).

I also really like Dungeon of Dredmor and Legend of Grimrock, so if you have anything like that ?

I also heard about Dead Pixel...
So... I'm waiting for your offers ^^
