So in order to better explain the concept of an open-world RPG to Japanese people, Bethesda had Fallout 3 demade into a very Dragon Quest-like flashgame while still retaining some of the core elements of the Fallout series. Like most flashgames whose sole purpose is to promote a retail product, there isn't a whole lot you can do (especially if you don't know Japanese), but it's fun to play around with for a while.

And yes, it totally has Dragon Quest-style command-based battles -- though instead of the usual commands you select different body parts.
 

I tried messing around with this but not having any Japanese led me to give up on it pretty quickly. It was interesting though.

I have a hard time believing Bethesda had anything to do with this.

" I have a hard time believing Bethesda had anything to do with this. "

I'd love to play some Fallout Warrior 3.

"Has there ever been a JRPG that allows you to target certain body parts in combat (apart from boss battles), I can't think of one. "

I can read some japanese but I started getting lost a few statements in. Looks awesome though and if they localised it into a £2 or £3 game on PSN, XBLA or iPhone I would probably buy it!
