I played Drawn around the time it was released and thought it was okay as an adventure game but far better than most other casuals. In only a few years many casual games have surpassed Drawn so I for one am not surprised that Drawn isn't way up there. It's just not the casual equivalent of, for example, the Gabriel Knight games.
Drawn is one of few casual games that I actually remember -- one of few I replay. So many casual games are similar to one another, and usually I can't remember much at all about a casual game, even as little as a day after I finish it.
Newer games may have more options, like custom difficulty, but the options don't work 100%. I've yet to see one that truly got rid of the so-called "helpful" (actually annoying) messages blocking my view of the screen, even if the option to disable them is there. Not only do they block the screen, but it's insulting -- like the game is calling you a moron. Imagine exploring a haunted house in real life and having these damb boxes pop up in your face: "Oooo!! You found a corkscrew!!" "You found a pin !!" "You found a peanut !!"
A lot of the once-reliable series have become inconsistent in quality, sometimes due to change in developer. There has not been any gradual improvement for quite a while. For example, I've seen a lot of people saying Mystery Trackers: Four Aces is their favorite of the series, and it's certainly not the most recent -- it's over 3 years old. The most recent House of 1000 Doors game, Evil Inside, was a huge step down from the previous ones.
Also if you buy a Standard edition, you often find it has the same menu as the CE -- only with dead options or ads. For example, where the CE would have brought up a guide, you find clicking on "Guide" causes your web browser to open and display an ad to buy a guide. To me that just looks sloppy -- makes it look like you bought carelessly thrown-together junk, or paid money for some sort of trialware. And then there are the ads for Facebook and Twitter that have invaded the Menu Screens of so many Big Fish games. The only way to avoid that stuff is to buy an older game from before they started doing that.
But back on the topic of favorite games ...
Most of the games in my list are older ones...
Big Secret of a Small Town
Bluebeard's Castle: Son of the Heartless
Dark Hills of Cherai: The Regal Scepter
Dark Strokes: Sins of the Fathers
Dark Tales: Edgar Allan Poe's The Black Cat
Dracula: Love Kills
Drawn 1: The Painted Tower
Drawn 2: Dark Flight
Ghost Towns: The Cats of Ulthar
Margrave: Blacksmith's Daughter
Margrave: Curse of the Severed Heart
Mystery Case Files: 13th Skull
Mystery Case Files: Fate's Carnival
Mystery Case Files: Key to Ravenhearst
Sherlock Holmes: Hound of the Baskervilles
That's 16 games.
I have a couple of casual games I haven't played yet, and may play over the weekend.
List of series:
1. Dana Knightstone
2. Grim Tales
-- the ones where you play as "Aunt Gray" saving her weird relatives who live (or used to live) in a castle
3. House of 1000 Doors
4. Mystery Trackers
5. Fantasy Mosaics
-- especially from #4 onward (the ones where you change color while solving)
