Drawing in 3D feels to me to have the same skill level as 2D, be it pen and paper, brush and canvas, or a draw pad. I'm a shit artist too and 3D feels just as hard as 2D. Tilt Brush however still allows me to make something cool with with very few actions, even if the final result is very simple. I highly recommend any person who can draw or sculpt to try Tilt Brush. For anyone else it wont have a ton of value. It's just shiny and neat I guess. I got it for free and am very happy to have it.
Job Simulator is hilarious and very well done. But I see no replay value in it. Playing it again actually feels like a job. I hope that they will just keep adding more jobs so it stays interesting.
Fantastic Contraption seems to not get any attention. It's a great game though, if you like engineering and solving puzzles. I do, and solved all 50 levels and logged 18 hours in it. But when looking at the global steam achievements, very few people actually bothered with the game at all. Only 50% finished the tutorial. I guess that people just don't like engineering that much. And some of the levels are quite hard to solve. When playing it, it reminded me of Besiege, which is a very similar game, and also is more fun to be honest.
