To you perhaps, but to a lot of people who enjoyed WFRP1 and are now enjoying WFRP2, WFRP is so tightly integrated into the game world, that it's as much 'playing in the Warhammer Fantasy world' as playing 'the Warhammer Fantasy Roleplay' system.
The Warhammer Fantasy world is one where combat is deadly, a world where insanity is waiting for you, disease isn't something you just 'cure disease' on, and a world where Magic can make you mad - or worse. And it's a world fated to end when the chaos gateways collapse. When that happens, it's game over. Nothing survives, and nothing that anyone does will matter one iota. You can fight the forces of chaos today, tomorrow maybe, but in the end Chaos will win, since the only powers that could fix the gateways are gone.
That's a pretty grim world from where I sit.
