I think it is safe to say that no other good moves exist :P
But seriously there are definitely some better opening moves than simply always moving your knights out, I would suggest looking up an opening you think suits you (the ruy lopez is a popular one) and learn a few lines into it.
But really knowing the technical openings is of minor use to a beginner.
I allways start with getting my knights out but are there other good moves. I always think of changing that stradigy but I never get around to it
