I want more Thief games.
Nothing fancy, no 'tweaking with the formula' or 'making it more accessible' or anything else of the sort as the new game will undoubtedly have. Just a straight up continuation of the series. Better graphics, same gameplay.
You know what? Make it a spinoff. I like Garrett and all, he's a grand character, but his story is done and frankly by this point I just want more of that gameplay style and setting. There hasn't been a single decent pure stealth game since Thief: Deadly Shadows, and even that was a step down from the previous Thief games!
Thief was the last and only of it's kind, and it's such a damn shame because Thief was really onto something...
