So would this count under suggestions or other? Anyway:
So I was playing this and the Mobile game (that side scrolling beat-em-up one only released in Chinese) and thought that it would be really cool if you guys made a retail game using the assets used for this game. Maybe something either sprite-based or a 3d game (These sprites look just like posed versions of the models from the Ultimate Ninja Storm games. Correct me if i'm wrong, but I suspect they actually might be modelled and posed as opposed to the sprites being made from scratch).
Maybe like a bigger beat-em-up, an RPG, or a 2D Arc System Works-style fighting game (with these sprites, I'd say it's definitely possible), or if 3D, even a Musou/Warriors styled game (with the generic enemies being the hordes of mooks to fight, like the Melee Forces, Archery Forces, etc).
The newer characters/costumes added into this online game in future updates could be DLC.
Maybe even have social link-style interactions with other characters (like you do in the Player Home, but with a bit more dialogue and effects than just answering a question you may have already been asked).
To be honest, I really like the variety of characters in this game (including seeing many characters playable that otherwise aren't playable in games (if they appear at all), like Dosu/Zaku/Kin, Zori/Waraji, Mabui, Mist Swordsmen, Ginkaku/Kinkaku, and the ones in the Chinese version (like Pakura, Toroi, Omoi, Samui, etc.))
And not only that, These player avatars are surprisingly well developed:
They not only have the character bios (from the original site, but can be read on the Naruto Wikia under "Naruto: Ultimate Ninja Online"), but also the character portraits in Story Mode and lines that can be seen in some parts of the game like the Hot Springs that further develop their personalities.
Scarlet Blaze is a hardworking, pragmatic person (who seems very confident) that is interested in various forms of Ninjutsu, and may be a tad vein judging by how he enjoys looking in the mirror, and his character bio mentions his striking appearance. He uses fire and sealing Jutsus and is more of an *ytical fighter.
Azure Fang is a compassionate, fun-loving & slightly shy person (who blushes a lot) that likes cleansing short blades and bathing. She has great Chakra Control which is utilized in Medical Ninjutsu, Water Style & Poisons, also reflected in her dream to heal incurable diseases in the ninja world.
Crimson Fist is a honest and reliable man who enjoys plant cultivation and uses Earth Style Techniques along with Taijutsu. Judging by his hotsprings talk, he enjoys snacking and massages. Sort of like a gentle-giant styled character not unlike regular Jugo (without Curse Mark influence).
Midnight Blade is kind of an antisocial person (as well as cool and quiet) that enjoys counting money earned from his bounty hunting jobs where he assassinates his targets. He uses Lightning Kenjutsu who doesn't waste time and just goes straight for the kill.
Breeze Dancer is a temporary Student of the Academy who has travelled a lot that has a unique perspective on society, and enjoys gazing into the distance. She seems to be quite more outgoing and flirty than Azure Fang if her knowing Harem Jutsu (and her dress sense in the majority of her costumes) is any indication. She fights like a combination of Naruto & Temari.
There was a few things I didn't mention (people they wanted to fight, Height, Weight, their favorite/least favorite food & blood type), but they're more developed than the majority of the anime-only characters and even some of the lesser canon characters. So I think it's a shame they're restricted to a browser game that requires online to play, and would like to see these guys in other games. I mean you do have permission to make official Naruto games if this is any indication (and since i'm positive CC2 worked on this too, I'm sure it's possible).
I'm sure you guys can make a great non-online only game. :)
Have you ever thought about this? What are your thoughts on these ideas?
