Run "MM7Setup.exe" in video settings select "Software 3D" then play.
You will see NPC's are different colors and clothes. But Spell Graphics are very bad.

When you choose "Hardware Accelerated 3D"

You will see All NPC's are the same color so you cant know which monster(especially master of sword,champion of sword)
(In sofware 3d-Master of sword's color is red and champion of sword's color i blue)... In Hardware Accelerated 3D these two NPC's color is same. You only know which monster is that you must use right click

But Spell Graphics are very good.Especilly fireball.

-------------

Can there be a way to make...

1-Spell Graphics must be good
2-NPC's colors must be different.
