A delayed game can still be great, but if you release a broken game, people will always see it as a broken game. Unfortunatelly CDPR felt pressure to release in 2020 and they did not deliver on their "coming when it's ready" promise.
Luckily for the fans, they did deliver on their promise that they will continue work on the game and now after Phantom Liberty it's such a gem!
They tweaked and polished the game mechanics. The customization stuff that seemed overwhelming is now very accessible, you can no longer abuse stim packs and grenades, until you run out, now they are infinite and cooldown based. Most of the glitchs and bugs are nowhere to be seen.
The story writing, the characters, the feel of the game and the graphics are TOP.
If you haven't been playing the game in it's previous sorry state, it is a must play right now, while you're waiting for GTA VI.
