Online has really helped me gain a foot hold in this game. I mean thanks to playing online I was able to cut through R. Ludroth, Gobul, Barroth, Lagiacrus, Rathian, Gigganox and Great Baggi like cake. I am most likely going to take on Rathalos, Barioth and possibly Diablos soon.
Here is a list of the monsters in Monster Hunter Portable 3rd:
Confirmed MHFU monsters: Anteka, Bulldrome, Bullfango, Rathalos, Rathian, Diablos, Nargacuga and Tigrex.
Confirmed MH3 monsters: Bnahabra, Great Jaggi, Great Baggi, Qurupeco, Barroth, Gigginox, Agnaktor, Rathalos, Rathian, Royal Ludroth, Barioth, Uragaan, Diablos, Giggi, Altaroth, Delex , Rhenoplos, Jaggi, Jaggia
New monsters include:
Gagua (Bird Wyvern): An ostrich-like minion commonly found in the Mountain Stream
Aoashira (Pelagus): A blue bear monster with powerful arms
Jinouga (Fanged Wyvern): A thunder wolf wyvern who is quite agile and uses lightning to power itself up
Urukususu (Pelagus): A white rabbit-bear monster from the Tundra region who uses its belly to slide around
Dosufurogi (Bird Wyvern): Similar to the Great Jaggi, this alpha raptor uses poison stored in its neck sac.
Furogi (Bird Wyvern): The Dosufurogi equivalent of Jaggi
Black Tigrex (Flying Wyvern): A Tigrex subspecies in the volcano with a greatly upgraded roar
Zuwaroposu (Herbivore): A green rhino-like Herbivore in the Flooded Forest
Hapurubokka (Leviathan): A desert Leviathan similar to Gobul in structure.
Rangurotora (Pelagus): A volcanic Pelagus that looks like an Armadillo. Rolls and attacks with its tongue.
Barroth Subspecies (Brute Wyvern): A subspecies to the Barroth thats covered in Ice and lives in the Tundra.
Royal Ludroth Subspecies (Leviathan): A subspecies to the Royal Ludroth that is colored purple with a pink mane.
Qurupeco Subspecies (Bird Wyvern): A subspecies to the Qurupeco This subspecies has no visible thoat sac and an array of different colors.
I am sure that it would not take much effort on Capcom's part to port this over to the 3DS in time for Japan and Western release date window. It would be a day one purchase for me if it did happen.
Also, how does the online component of the series work on portables?
