If you're playing a quick-kill strategy, this is the
one secret project that you really, really want, even if you normally think
projects are for wussies. It's cheap, and it comes early in the game ( so you
don't have to mount a big research effort to get to it, plus it's attached to
a tech that you want anyway). Most importantly, the moral boost you get from
it will make it alot easier to charge screaming across the continents, sweeping
the hapless enemy before you like the puny vermin they are.
Which dosen't mean that this project is useless to a
peaceful faction. Far from it. Eventually, somebody's going to try to push you
around, and having this project behind you will make it that much easier to
push back, while in the meantime allowing your baes to concentrate on expansion-related
development instead of building command centers "just in case". In
fact, at this price the Command Nexus is probably worth building just to keep
a more aggressive enemy from getting it.
Obviously, the usefulness of the Command Nexus is undermined
a bit on watery worlds, where most of the action is liable to be naval. In that
event, your energy and resources would most likely be better focused on building
the Maritime Control Center.
With universal utility and no downside, this project is definately worth making
a high priority. Do, however, expect some fairly serious competition for it
from the other factions. Expect to spend some cash to hurry it a bit, if you're
really serious about getting it.
