I have fond memories, but lets be clear, it has some of the worst puzzles in lucasarts history. Some of them are pretty obtuse, and the backgrounds often don't make clear things are selectable.
It's a shame as with better puzzles (and an actually finished game, it has a big chunk cut), it would be one of the best. The story and characters and world are fantastic. I think that's pretty much par for the course with Schafer, that's where his talent lies, you can see the same thing in Grim (and from what I hear broken age, I never finished it as I was so disappointed by the puzzles).
I think if he did a collaboration with Gilbert or Grossman again you'd see something really special.
Depends what you liked about Throttle I guess. Some great adventure games from after the golden age:
Thimbleweed Park (the best, made by ron gilbert)
Ben There, Dan That & Time Gentleman Please (funniest P&C games since the lucasarts golden age - only play if you like british humour though. Dirt cheap bundle of two games)
Lair of the Clockwork God (P&C/platform fusion made by the ben and dan dev. same condition applies)
The Book of Unwritten Tales
Dropsy
Primordia
Blackwell series (5 game series, first 4 are available in a bundle)
Technobabylon
Kathy Rain
Shadowgate 2014 (remake of the original, so only play if you don't mind dying quite a bit)
The Shivah (super short)
It's amusing that wrong gilbert does actually sound like ron gilbert phonetically lol
