Critical MELT

Would love to keep playing this on my PS4. It has so much potential to be a simple open world-type adventure game to go on so many different quests, but there's way too much LAG while the fighting intensifies in the dungeons. It's actually crashed the app 3 times. And that's not even touching on the error message I keep getting every time I try to access this new "My Room" that I acquired? "ERR_03002: Could not find server." Tried looking it up but nothing comes up for this error so I let it slide in the meantime so I could try the rest of the game. After this lagging though, I think I'm just going to stop because it doesn't feel like I'm going to be getting anywhere with it. Thanks, but no thanks, unfortunately.
