Epic War 4 was better because:
1.i like to buy units so i don´t have to wait as long for a special unit i want
2.its a bit too rpg style . these skills and equip isn´t soo good for epic war (I WANT MAGIC :.( *sad face* )
3.the new hero system its better for me to have 3 heros i like this more than one
4. i don´t know
otherwise a good game
