I have several suggestions. 1.  When you order a group of soldiers to attack a building, let them stay in their formation instead of spreading all out and letting the horses get there first. 2.  Let players be able to select more units at a time.  I found you can only select so many units at one time, so I had to make like 3 groups of soldiers for an attack. 3.  Make a government (kings and queens, leaders, councils, depending on the different civilizations) 4.  Change the attack style of computer players, because whenever I play on a team with another computer, there's always another team/teams that continually attack my team and barely attack other teams 5.  Add a library or research center so you can advance in technology 6.  Add buttons so you can communicate with computer players on your team (such as their style: attacking, balanced, defending)
