The comparison to a WW2 tank in the Black Forest isn't great though, because the environments live on different timescales.
A forest can regrow and thrive after a few decades. The same is _not_ true for the deep sea[1].
'Life on the ocean floor moves at a glacial pace. Sediment accumulates at a rate of 1 millimeter every millennium. With such a slow rate of growth, areas disturbed by deep-sea mining would be unlikely to recover on a reasonable timescale.'
I had a blast with TIS-100 and Shenzhen I/O when they came out, but for some reason I never picked up Infinifactory until yesterday. I'm so glad I did.
Zachtronics games give me that feeling of zen that is increasingly harder to find in games nowadays - the "Oh dang it is 2am already, I thought it was like 9pm!".
I'd recommend checking out the aforementioned titles, as well as some of the 'other games' on the website[1], like Ruckingenur-II.
Although I don't see eye tracking in games as 'the next big thing' in any sense (the few I've tried were severely lacking in the fun department), I would be interested to try playing Soma with this.
Soma had some flaws to be sure, but damn did it do some things really well. I'd highly recommend it - eye tracking or no.
For what it is worth, numbers are not necessarily a 'universal concept'.
One of the most talked about examples is Piraha[0], a language which doesn't really represent numbers. This is interesting because a study done by Everett and Frank[1] shows that this can actually have effects on cognition, providing some evidence for the Sapir-Wharf hypothesis[3]
The biggest player that uses it is Unity, but even they have their own special fork of Mono to get it to play nice.
Full Disclosure: I work for a Microsoft/Xbox Studio.
