Are these custom rings possible on PS4 too? Still not sure if I should buy the PS4 version, is it good in comparison to the PC version? What are the negative things about it in a comparison?
Custom rings are possible on the PS4 - you have to download each piece (mat, corner pads, apron l, apron r) and combine in Edit Ring mode yourself, but definitely doable. I'm rocking the current NXT, RAW, SmackDown, ROH and Dragon Gate rings, myself.
The PS4 version has the NJPW DLC content which the PC does not. The negative side is that there aren't as many good creations/creators as on the PC, but it's getting better/deeper every day.
