since monster hunter in great demand
they should make an evolved version of monster hunter
i would call it monster hunter : future crisis
imagine it will be all be modern instead of old tech hack and slash
which will include all the current modern warfare, such as the commando rifle in snipersnake siggy

take away the hunter rank system and implement a fully experience point system which can be obtained through each killing/hunting
as the player level up, can upgrade more on weapons or buy new armor or obtain higher level monster bounty
a large map like usual rpg with random monsters around
take quest and finish it alone or coop with up to 8 people thru adhoc/infra
battle take place in real life places such as famous city for an example
monster will be more than predictable movement, as real as possible
