Kitchen Simulator 2013

Dark Souls

I think most adventure game will do the job. Actually, they're hidden objects game with items combinations feature, they also have story which are better most casual hidden objects game. And you already have many of them: Monkey Island, Machinarium, To the Moon (good story and soundtrack), Deponia, etc.

Play Torchlight 2 in co-op :)

Seduce me

amnesia

Braid!

My GF enjoyed FEAR 1/2/3 and Dead Space 1/2, but i suppose it doesn't really count as she plays a lot of games...

The Binding of Isaac, Super Meat Boy, Trine, Portal, Plants vs Zombies and Peegle.

I also a hidden object game player. But i love to play other games too so I looked your game list I here are some game that I play :
Tropico 3 - Steam Special Edition,Machinarium,Don't Starve,Deponia,Faerie Solitaire,Quantum Conundrum,Vessel,Alice: Madness Returns,Botanicula,all Broken Sword!!!,Cargo! - The quest for gravity,Cogs,Closure,Crayon Physics Deluxe,Hamlet,Kaptain Brawe,Roogoo,maybe Sam & Max 301,Spirits,The Path,Trauma,Unmechanical,

You have a nice collection of games :)

Leisure suit Larry. Oh yeah. My ex loved those games. Apparently they are great satire or something...

L.A. Noire. Quite an interesting mix between Looking for clues ('rather' similar to Point&Click Adventures) and a bit of Action. On sale at amazon atm for 10$.

hi, i think this title can be good ;)...4 elements, faery solitarie, crayon phisic deluxe, eets, puzzle quest (series), toki tori, zen bound 2, might and magic: class of heroes!!

edit... i have miss: cloning clyde, splice, spectraball, flight control HD.

my girl loves playing civ v. at first she was resistant, but then i got her to realize that it's just a board game.

My wife and I play Trine(1 currently) co-op. She also plays Spectraball and Sonic: Generations. All of these she plays on our TV with my old laptop using an XBox 360 Controller. She generally likes puzzle games on the PC (like MS' Tinker), and from Steam she plays Snapshot, Toki Tori, and Spirits.

I've put more games on her account than she'll ever play, though.

All that I can think off is that the girl of my dreams plays BioShock, Half-Life, Portal, Team Fortress, Left 4 Dead, Fallout, Assassin's Creed, Deus Ex and Metro. I'm sure that there is one anywhere in this world. One pale with short brown hair, same age or similar as I and more cute than attractive, the kind that my heart has always beating fast thinking about it. That's all I know about what kind of games a gf would play, I guess the one she likes?

i'd recommend any of the sherlock games or portal/portal 2

Worms Crazy Golf, Peggle Deluxe

"She is not a serious gamers and mostly plays hidden objects games."

Then she might like L.A Noire, the game has lots of hidden clues and all which you'll have to go through to complete the missions. She must give it a try. :)

Can you see what i see,The sims 3,hmm... portal,and SKYRIM(jk)

Similar issue with my wife. I put Faerie Solitaire and she loved it. Plus it's one of those games that doesn't actually need the Steam client to run, just to install.

I got Trine and Deponia for my wife.

My wife likes Fairy Solitaire. She also plays Heroes of Might and Magic III quite a lot. :)
