Grim Squeaker:

There's nothing odd about French companies making English games, it happens all the time.
Besides, offices and land in Northern America is as expensive as the first Rolls Royce. (Well not really, but you get the idea)
Besides, since Graal is the only MMORPG which allows completely custom development by players, they can still attract players, no matter if their offices are in the US or in other places.

Plus, if they did want to become partially based in the US, it'd be better to just hire a server and a sent a few of their staff to operate it, it's far less expensive then having to move around all the current servers and offices.
