Different development teams is different from different company. And even if it wasn't there still using the same resources, just adapting code to the console versions while making sure it all works well and adapting some controls and other things for consoles.
The controls are much more cumbersome on the console version, there is no support for mods, no dedicated servers, and the community itself is like night and day compared to PC, from everything including the overall mentality and gameplay style, to the size.
It's really like playing a different game.
