[rollems]

thanx loreangelicus i will play with easy now. and will use the units you advised

DGDobrev and Hento. i hear you but i am very very new also this my first turn based game, also i dont understand when you say Tanks, droids what are they ? are all units categorized?
is there a list where i can read about which units categories are available and how they perform against what ?

also when i enter a battle is there a way to know how a unit will perform against enemy type and what type. so i engage accordingly.

thnx guys for helping really appreciate it.
