I hate to be the reality check here but...
You realize that this would have to be done on OGMK2, whose servers are immaculately bad these days, since both players cannot random on MKAK? Not to mention, OGMK2 isn't available on the PSN Store anymore and the odds of finding eight people who still have it and are willing to random select in the current era... good luck is all I'm going to say. We're in the dark ages right now and only two things will turn it around...
#1 - The UMK2 rom hack, whenever it gets released
#2 - A re-release of the classic games with better gameplay on current gen systems (not going to happen anytime in the near future since MKAK came out only 3 years ago.)
Also, the UMK2 hack, at least seems, to be about finished. When it gets released to the public we can probably start doing something with that. Unfortunately this means the community will, as I predicted, be shifting from console to Kaillera, so y'all best be getting your PCs ready to go.
Kaillera lags worse than MKAK, I don't even bother with it anymore.
Also, unless the UMK2 hack nerfed Mileena, it is pretty much a joke.
Making her roll have to be low blocked, and easier to combo with, is definitely not nerfing her...
Any word on whether that has been changed?
Anyway, we CAN have a Randoms tournament on MKAK even though Player 2 can't Random.
This would be done by P2 always selecting the character that P1 got on Random in the previous match.
When I play guys online and we want to random, this is the method we use.
1st match would be just a warm-up, and to determine who P2 would be using in the 1st actual tournament match.
I hope that makes sense.
Finding 8 people just to play any kind of MK2 tournament will be difficult.
Couldn't even find 8 when there was a $500 prize LOL.
