Basic overview of game
As for comparison, if FSFG is a simplified Street Fighter/GG, PR is a simplified KoF
The character bio's are a bit dated, and a few of the characters have been redesigned.
Here's a current version:
Tenchi = Shoto, like Ryu , Ky , etc . Gains meter by using specials. Basic dash.
Naomi = Rushdown with no projectile, like Decapre / Cammy, Terry Bogard. Gains meter by pressing A+B to charge, meter is used for Ex moves. Has a run that can be shorthopped
Parker = Parry / Traps, like GG Bridget + SF4 Abel, can set up orbs to be used later. Meter is used for parry, if you miss, you lose a bar. Has a projectile invincible roll.
June = Ranged, like Dhalsim , Anarkaris. Gains meter by collecting spirits that opponents release after hit. Meter is used to activate a clone that repeats the last special used by June, and acts like a roman cancel. Dash is a teleport.
Sub11 = Moble Grappler, like SFV Mika , Laura. Gains meter by blocking, can be used to give Sub11 armor for one hit, and acts like a roman cancel. Has a crawl that gives low profile and has one of the greatest animations ever.
