And to be fair, it's not that good in the first place. Back at i37, all it really did with L4D was make the zombies look like sprites, not quite fitting into the game. I can understand how depth perception might help in some games (especially in the modern ones, where enemies don't really stand out all that much), but I'm not sure it's worth dropping a crapload of cash on something that's yet to be perfected. I think 3D's not going to be particularally good for another few years, so prehaps you should wait until the tech evolves, or the price comes down?
