I've been an avid fan of the game, but haven't posted in the forum yet.
My idea is to make the grappling system much more realistic and interesting. I don't believe this would be too technically difficult, though my understanding of programming is cursory at best.
Anyway, I've been doing Brazilian Jiu-jitsu, Muy Thai and Wrestling for some time and the wrestling system kinda annoys me, given the ability to grab someone's head with your lower arm while locking their knee with your upper arm, it dosen't make any sense.
Many of you may not understand what I mean by "mount, turtle, side control" and other grappling terms, but these can be easily looked up if you're confused.
Instead, overlay a list of relative positions, such as double-underhooks, guard, full mount, etc, and the other guy being "inside urist mcGracie's mount". The game could use the current system without too much change by seeing the position, say double underhooks, as both arms gripping the body. This will be even more useful with the upcoming update and less-than-lethal combat.
If you developers like this idea and want to implement them, I would be more than happy to help with the details of grappling.
Available grips would be changed based upon what you and your opponent are wearing.
Each position provides options, like so:
+ or - to denote the strengths of strikes.
Mount-to understand:http://en.wikipedia.org/wiki/Mount_(grappling):
Punch ++
No kicks
Choke
Armlock/Wrist/Shoulder locks
Transition to back
Transition to side control
Break contact
All locks and chokes have an advantage while in this position.
Inside Mount:
Punch -
No kicks
Some locks available but with massive penalties.
Escape to halfguard
Escape to back
The grappling system would almost be a flowchart, and these positional transitions can be implemented in a very simplified or very detailed way, for example-
Simple: Takedown/Throw->Back->Armlock
More detail: Grab wrist & shirt->Over/under hooks->Double underhooks->Suplex(Throw)->Turtle Position->Turtle with hooks in->Back->Armbar position->Armbar
If you're not familiar with MMA, BJJ, Wrestling etc this might be very confusing, but would be extremely interesting. Again, I've competed quite a bit as a blue belt in BJJ and am happy to help with any of the confusion.
EDIT: No make this easier to understand, I added two flowcharts which illustrates the transitions between different positions and how the system could be made very simple or very detailed.
