How far of a graphics update would you go? Upgrade to Windows 10 with direct x 10, 11, 12?

I would consider the users of this game that have mobile devices currently that can support what your vision would be.

I would then move to re-do the website that is less of an arcade and move to a more suave or sleek looking website. This might increase the numbers of the game at a first impression.

and are you going to provide the thousands of $$$ that that would require ?
