I almost forgot my responsibilities playing this game!
But anything else... this is the game that I can play straight whole day! And I'm supposed to be doing something else. You can collect soldier like in Portable Ops (Or Pokemon), collect mech, build Home Base and more...
There's just so many things to do aside from the main story... You can even costumize using vocaloid and stuff...
The best part is, they mixed the game with my favorite stuffs! Like Assassin's Creed Leap of Faith and Monster Hunter... I was addicted to Monster Hunter first before this game... So I think MH kinda lift it up for me...
As a whole... this is worth every cents!
