i loved all 3 and the 4th is better the fact that u dont need to press to release troops gives you much more option with the skills overoll i give that game 4.5/5 if it possible or 5/5 if u will XD
I dont know what about the others but i find it hard to control my cell when i go forword it sometimes go fast and sometimes slow and i dont know why :L
nice game i liked it but i agree it could be better with graphics that will apear when you invent new stuff such as if u invent the field (earth+tools) there will apear a field on the map ... but still 5/5 great game
