Screeps is a fun game and has a unique angle to it.
Using actual programming instead of a pseudo-language actually
allows the players to focus on better coding habits and makes practice fun.
We use Screeps as a key part of our recruitment process at fleetster.
Screeps is useful because it throws candidates into an
unknown environment where the number of "right" solutions are very numerous.
It was fun while it lasted, and probably the best thing is that I really feel like
my Javascript and Node fluency has gone through the roof compared to what it was.
