So Big Fish, quick list of some stuff to consider. I'll try and edit and add to it. I slanted it a bit toward somewhat more obscure stuff because I figure the ghostly hidden object stuff they already plaster all over the front page.
Age of Mahjong
Antique Road Trip USA
Battle Slots (Sort of Puzzle Quest with slots; don't think about it too hard)
Best in Show Solitaire
Build a Lot games
Burger Island (for Sunasun; it's sort of like Cook, Serve, Delicious) Dammit, removed
Chocolatier Games Removed, ugh, this is the problem with having an old ass list. Anyway Half Price books may have boxed versions of it cheap
Ciao Bella (a rare romance sim/visual novel that's not Anime. Yes it's girly but it's quite good for the genre and unique)
Coconut Queen (if you aren't one of the 50 people I gifted it to; it NEVER goes on sale on Steam anymore and it's awesome)
Cute Knight (By Hanako, sort of VN/RPG-lite)
Cute Knight Kingdom (another from Hanako)
DQ Tycoon Removed
Dragonstone
Drawn games (probably Big Fish's flagship game. On Steam but NEVER goes on sale)
Elementals: The Magic Key
Emily's New Beginning (Recent release, reboot of a well known time sim casual serious)
Fairy Godmother Tycoon (quite detailed for a casual game; 67 reviews and at 5 stars)
Feeding Frenzy (Popcap)
Fishdom games (Depths of Time is the newest)
Mahjong Escape (Popcap; there's Japan and China versions)
Murder She Wrote (Has voice acting; the person they got does an excellent Angela Landsbury

)
Press Your Luck (Ubisoft seems to have removed it)
Nancy Drew: The Silent Spy (This one is not on Steam it was released in 2013 after they stopped releasing on Steam)
Plant Tycoon (Utopianmachine got this one with her freebie)
Seven Seas Solitaire
Scrabble (Popcap)
Sheep's Quest (Unique game, kind of hard to describe. Puzzler with building mgt elements, sort of boardgameish too)
The Chronicles of Emerland Solitaire
Wandering Willows (Utopian Machine's top pick
. On Steam but never on sale anymore) removed

(
Wonderland Adventures: Mysteries of Fire Island (3D top down puzzler kind of indie-ish visuals but had its own charm)
Youda Fisherman (time management with boats)
They do have some more famous stuff too like Puzzle Quest and a bunch of the more well known Popcap games.
Oh gosh, I think that's like 80% of the Hidden Object games there which themselves are like 80% of what they sell. Let me think on it.
