If I can ever muster the courage to finish Doom 3, I'll have to give this a look. I still think the grabber is the first in a long line of gravity gun knock offs that we'll be bludgeoned with over the next few years. If it is the price I have to pay for the glory that was HL2, so be it.
If they all do it as well it was done here, I won't mind too much. I thought the grabber in RoE was actually better balanced with the rest of the game than the gravity gun was in HL2.
