Why are multiple engines different?

There is quite a bit of info about single engine performances
though. Nothing specific about taxiing with one engine I
must admit, but there are a lot of other things that are
omitted as well, for instance, take off performances
with the wings off, that sort of things.

Well, the advantage of simulation is that you can easily try these
things.

But once stopped,
or sufficiently slowed down, I guarantee you that you
won't go anywhere without pushing or towing it (in the
conventional light twin, well in the glider too)

Increase the throttle very slowly, and wait for the plane to start
rolling. You won't spin around. If the eccentric thrust is weak
enough that the nose gear can compensate for it, you should be able to
taxi, but it will be an extremely slow taxi, and it will take a long
time to get rolling.

A flight sim that has reasonably good models is Xplane,
which you may want to check out,

I still haven't been told what's wrong with the MSFS model.
