I have played Thief 1/2/3 and over a hundred Thief 1/2 add on missions. Thief's 1/2 Magic Ingredients were....
There was sophisticated programing for Thief 1/2. Light and sound mattered to the AI. There were locks, puzzles, contraptions, levers. Garret could use the rope arrow on any wood. Garrett could swim.
Thief 1/2 were made in New England, where Thief 1/2 was made, has a marked Autumn season. Notice how many leaves are strewn about in Thief 1. As someone from New England who now lives in Northern California, I will state that it's hard to imagine how creepy it is to be in a graveyard at night around Halloween, when you are a child. In Thief 1, that graveyard, is in the middle of a haunted town that you will have to make it back through, and yes, but you still have to go under it.
There were quite a few women working at Looking Glass Studio on Thief 1/2. It wasn't made in an all-male cloistered monoculture. Women make add-on missions. Women even cos-play Garret. If you want women to buy video games, hire women.
The biggest problem with the Thief reboot is the console game culture, where games cannot require skill to play. Ref: http://www.youtube.com/watch?v... You cannot move like a "Master Thief" unless you can control a character.
Sadly, Looking Glass Studio failed. Thief 1/2's (as well as SS2) biggest problem was it's graphics were very polygonal even for their time. Thief was never a breathtaking game visually, but once you got over that it didn't need to be, and that is why there will be many more missions for Thief than there will be for most newer games.
I might check out the new Thief, but for missions, I'm not expecting a mission as excellent as Ominous Bequest, or The Seven Sisters, or a story as good as Saturio Returns Home or The Bathory Campaign. I'm not expecting the care and devotion shown in Thief 2x or The Dark Mod.
Still, I hope there is enough in the reboot Thief, to go admit their faults and go on to get everything right.
