MK11 is probably my favorite MK out of all of the NRS MK games, so far.
In close second would be MKX, for me.
MK11 made me care about characters that I never really gave a shit about from MKII until MKX (gameplay-wise) like Shang Tsung, Sindel and Nightwolf.
The kustomization options and SP modes have been much more fun for me in MK11 than they ever were in MKX and MK9, with the exception of maybe Tag-Team in MK9.
I also prefer the Brutalities in MK11 much more than the ones in MKX, too.
Yeah, I know that MK11 may not be everyone's cup of tea, but I sure as hell have been enjoying it.
Can't wait for Fujin to finally be playable.
