Tips

Tip 1

     If  it's possible, maintain a money reserve of at least 10,000 to
15,000  gold pieces. This fund can be used to buy armies out of fights
they  just  can't  win.  This way, you won't lose all your hard-earned
units.

Tip 2

     On  the  larger  maps,  use  one  or  two  token heroes with fast
movement  rates  to  move  units  up from your cities to your powerful
heroes out in the field.

Tip 3

     In  most scenarios time is of the essence. While you are building
up  strength,  the  computer  player  is  busy  building up one or two
massive  armies.  Find and destroy them early on, even if it takes two
or three armies attacking in quick succession to do it.
