A glorious nostalgic concept, bring back the pit one for mk6. either in original 2d (ish) form or a 3D version - so long as it stayed as thin stretch of concrete. In my opinion the best stage in MK history; so simple yet so great! However i wouldn't want to see an 'Uber' pit 1, like a re-vamped version, just keep it plain and simple. Pits are the best fatalities in my opinion (not roof spikes though). I'll stop now. Cheers.
the pit in 3d would be great, all youd have to do is make the bridge wider , so that you can stay on but its tough , so you dont watn to get knocked around too much , you could even have the characters able to grab the ledge and pull themselves back up if you mash the buttons.....?
