Awesome guys! The lobby thing is in the left most tab for the PS4 community thing, and I'm pretty sure anyone can set up a party/lobby, I'll also update the header and put messages up. Look forward to playing around/training/grinding multiplayer trophies with you guys!
Gohastings has another 50% off used sale, noticeable niche games:
Blazblue Chrono Phantasma Extend (PS4) $50 /2 = $25
Deception IV: Nightmare Princess (PS4) $35 / 2 = $17.50
Kingdom Hearts 1.5 HD Remix $15 /2 = $7.50
Evolve Ultimate Edition (PS4) $55 /2 = $22.50 (not really niche but good deal)
Keep in mind they have like 1-2 copies, so it'll sell out really quick, probably within seconds once someone sees this. Good luck!
