The same people who did N3 is also part of the team who did this game AFAIK.
N3 was a pretty mediocre game by any standards, so I guess I'll have to wait for reviews.
Not from Gamespot though. Lol.

Synthing basically transfers abilities from your old equipment to your new one. You also level them up this way.
e.g: Synthing a Bloodlust 1 Gauntlet with another Bloodlust 1 Gauntlet will get you a new Bloodlust 2 Gauntlet.

I think the game is rather mediocre, and it has less of a plot than Diablo 2 (if that's even posssible), I don't even know what the hell is going on in the game except "KILL MONSTERS".
Eh, its a half-decent hack and slash. About as fun as N3.
