FPW is not a difficult game it is just different when compared to more traditional games like Here Comes The Pain, or WWE 2K16. FPW is a time based game and depending on the button combination you press as well as the timing the game will determine what exactly happens. Because of this I need you to throw out everything you learned from other games that arent FPW related. Because FPW is a much different game, but once you get the hang of it, it is one of the best wrestling video games of all time.

Unlike other traditional wrestling video games the grappling system is done automatically as opposed to having a dedicated button. Just stand next to your oppenent and the wrestlers will grapple eachother.

Now for the timing element that makes this game so much fun,
When the wrestlers go for a grapple, as soon as there hands touch, that is when you want to press a key combination. Key combinations can be anything with:
X - Small attack
A - medium attack
B - Strong attack

Also combined with moving the left joystick in whatever direction being Up, Down, Left, or Right.
Dont button mash and make sure you rpess both inputs at the exact same time, dont try to hold down one and then time the other. Learning the timing is key to success.

As for other keys and things to remember:

When your character is tired holding LB will let them breathe and they can regain stanima that way.

Down + Y - will allow you to pick up weapons

When in a grapple pressing Y will Irish Whip your apponent wherever your joystick is facing.

RT - will allow you to pin your apponent.

X - near the ropes will allow to exit the ring.

X - near the apron will allow to climb back into the ring

X - near the corner will allow you to climb up the turnbuckle

X - in a cage will allow you to climb up the corner of the cage

X and down - on a downed apponent lifts them up

LB - in the corner near your ally (in a tag team macth) will allow you to tag your partner in.\

Finshers - are unique and different for every wrestler. They can be mapped to different keys.

The first thing you need to do is subscribe to the wrestler you want in the workshop.

Load up the game after it's done downloading (that shouldn't take long)

Then you need to add the wrestler to your game. Go To:
Edit Mode > Wrestler Edit > Create New Edit> Model Wrestler:

Then find your downloaded Wrestler and save it (it should be at the bottom.)
Save it to a [NEW SAVE]

IF it asks you to put it into a Team just use Retire (unless you want it on the SWA roster)

Then go to Team Edit > Transfer Wrestler > and then select the brand you want. (from RETIRE becauses thats the one we selected earlier.)

Also to create your own brand go to:
Edit Mode > Create Team > and then make sure the team size is Promotion. You can move wrestlers to is as long as you make a stable inside your main team (I ussually name a stable All Wrestlers and then put it on the brand team) you do this because the game wont allow you to just put them on the brand team.

This is definitely not a finished guide at all. I will add more information as I figure it out. If you guys have more useful information that you feel needs to be added then add a comment and I will get to it ASAP. If you would like to ask me questions then go ahead and message me, and again ill try to get to it as soon as possible.

Have fun with the best wrestling game of all time!

First Edit: Thank you LoneWolf for figuring out more information!

- X(SML) near head = Get the opponent up
- X(SML) near lower part of the body = flip the opponent (face up / face down)
- X(SML) near legs while the opponent is face down = Get the opponent up facing backwards (you can do back grapple while the opponent is up)

- Y(RUN) either near head or legs = drag the opponent around
