Ok, I try it, but my english is not fluent at all xD.
monster hunter is a RPG type game with a clear objective: kill monsters
, in a difference with other RPGs you can't up level, so the any way to become stronger is making better weapons and armors.
you can also chose differents types of weapons, great sword, sword and shield, lance and shield, hammer, switch axe (can convert into a sword), long sword, and bowgun
the game has 2 principal modes, offline and online, the offline has a duration of moreless 50 hours, in online, you can play with 3 players more and hunt in group.
