The game is worth every single penny , per se .

There are a lot of bugs and glitches but given the amount of content this game has , it should not be a surprise .
Given CDproject's track records , I am not worried on the bugs and glitches . I am fairly sure they will eventually iron out most of it like they did with Witcher 3 ..
Problem is just the PS4 is struggling really hard to fit the whole game into its 6 - 7 years old hardware . I am not sure it will ever be smoothly playable on PS4 ./

The situation is less severe on PS4 Pro after the latest patch . There are still hiccups here and there but I think the PS4 PRO should be perfectly capable of running the game given a few more optimization patches .

After the latest patch , the game seems to have hit a really sweet spot on PS5 , almost fully locked 60 fps [ obviously don't compare it with game running on PC & Rtx 3090 ].
