I was excited to rediscover my stored copy of Kerbal Space
Program while rummaging around on my cd's looking for
something else. Visions of space rockets and orbital
mechanics and Kerbal glory danced in my head, and soon I
stuffed it into a corner of my barely-functional "Windows
10" machine,
(actually a used Windows Vista era laptop
that didn't totally choke on 10).
After playing with it awhile, I've come upon the realization
that it's all... well... a bit boring for being hard, which is
disappointing for such a finely-crafted physics engine. Fly
here, fly there, orbit this and that, take some atmosphere
temps, try and land on Laythe and Eeloo... it suffers from
the same tedium of trying to back up an over-large trailer
into an tight RV campsite using some tiny mirrors, your
speedo, a watch, and a GPS.
Enter the bad guys who are subject to the same physics
you are. They could from the evil side of Kerbin or from
some other extra-system planet altogether. Design a
weapon to throw some well-aimed asteroids at their ship
before they destroy your space station. Claim Laythe
planetary territory before they land there. Save Kerbin
from the virus they bring with them by preventing them
from landing.
Maybe some enterprising modder could set up a
multiplayer mod designed with a competition in mind. Are
*those* Kerbals trying to fly to the Mun before your Kerbals
get there? Plant some spies and sabotage their rocket
design, or send a space-plane kareening at ther launch site
to knock it all down.
