When The First Two Pits Merge Into One Pit

One of the most interesting aspects of Mortal Kombat (2011) is how the Pit stage is presented in that game. You may notice that the first two pits were actually merged. The actual combat happens in the first bridge while there's a second bridge for two other kombatants. What's truly weird is that you may realize that the bridge is located in Shang Tsung's Island - NOT Outworld. Yet, the second bridge was in Outworld.

Older fans who played Mortal Kombat Trilogy (a game which aged rather badly) is that there were the first two pits. The first pit and the second pit were added into the game. The game being mostly copy/paste with some unused boss sprites (ironic that Goro shouldn't have his stomp move) couldn't integrate the original Mortal Kombat II pit fatality. The "3D effect" of the enemy falling down needed unique sprites. Granted, there could be editing of sprites done (which is done by some fan gamers) but I think memory space and time constraints is the real life writes plot. 

The second Pit made it into the adventure game Mortal Kombat Shaolin Monks. It was part of the Smoke quests which would unlock the original Mortal Kombat II arcade game. Knocking down the soldiers would recreate the scenario of falling to the flat ground. The simplicity was genius. The fatality, however, was soon removed.

Mortal Kombat (2011) managed to merge the two pits. You had the darkness of the first pit and also the spikes at the bottom. Yeesh! I guess the designers felt that recreating the flat ground finish wasn't as satisfying as IMPALING someone. Then it made me think why in the world wasn't that done with Mortal Kombat Trilogy instead? They couldn't do the second Pit's original finish so why not create a new stage fatality to take its place instead?

Eventually, Mortal Kombat X decided to implement it with a different finish. This time, making use of the pillars to give an extra gory finish. I was thinking why wasn't the stage added in Mortal Kombat 11? It was surely in Shang Tsung's Island so why not add it as an extra bonus? I mean, we've got Cary Hiroyoki-Tagawa after all, right?
