GW, for all the "well, they just copied Tolkien and TSR!" the get, and often deserve, did do something original and fun with Blood Bowl in the 80's. They certainly took a gamble on what was an odd sounding choice at the time, and deserve some credit for it, and certainly deserved it to become as popular as it did back then. I'll be thrilled if Mantics game turns out to be something really original, so I'll wait and see. So far they have never done so.
There's a difference between "100% express negativity against everything Mantic produces" and just being unimpressed with (100%? Maybe) what they make. I reckon Uncharted seas from Spartan Games owes a lot to Man 'o War, but there you go, I'm quite into it. The fact that I still check out every new Mantic release, along with some of the supposed haters I guess, shows even "these people" hold out hope.
