You can easily mod that game from older gen Consoles or even use a STARTER SAVE perosnally get the new SAO GAME ITS beast. and has active PVP and quest,
I don't have older gen console, just a ps4 and xbone lol. I beat sao lost song when it came out, just wanted to play it again been so long. The level up thing is nice but even at level 1000 it just brings up your hp and mp and some defense, doesn't increase your stats etc feel so weak still lol.
