The Japanese version is out -and has been been patched to offer full English text and voices, if you want to get it early- and it is AMAZING. Arc has recreated the look of GG perfectly using polygon models. These look so much like sprites and the 3D camera views added to certain supers and instant kills are just insane. The visuals look like something ripped right out of an anime.
Game play is similar, but I would describe everything as more accessible now and all of the characters feel pretty easy to pick up and play, especially newcomer Ramlethal. Haven't tried the other new character, Bedman, yet. Jeers to Arc for making the other three newcomers DLC, however, and as of this time none of them are available yet.
I've been messing with all the characters and really like the way Ramlethal, I-No, and Chipp play. I usually tend to go for the faster characters or the bigger grapplers, but Potemkin feels weird to me. Maybe I just need to use him more. I've always preferred BlazBlue's Iron Taiger to Potemkin though.
Online offers pretty much every option you can think of and the game is cross-play. Most of the people I played online were PS3 players, in fact. The PS4 version is arcade perfect and runs at 1080P/60 FPS, with some of the cinematics and super moves dipping down to 30 FPS or lower. The PS3 version is 720P and apparently offers PC-like graphics options, with a performance option disabling background animations to offer 60 FPS, and a more graphics-oriented option that runs at 30 FPS. I'm not sure why anyone would want to play a fighting game at 30 FPS, but it's cool that they offered that option and to my knowledge this is the first time any console fighting game has done this.
There's a big story mode in the game, but I haven't tried it out yet. The game recommends playing through arcade mode first. Have been messing around in training mode and played online, most against Japanese players. The netcode is typical Arc, I.E. great. Finally something to get me playing my PS4. Anyone else getting it?
