if you mean flop sales wise id say no, the original currently stands at 2.6m and i think fable 2 will easily pass this with the 360 being more popular than the original xbox.
if you mean review wise id say no again. edge magazine (very well respected mag in the uk) gave it a 9/10. to put this into perspective they gave fable an 8, mass effect 7, metroid prime 3 7 and bioshock 8.
