my biggest issue was the bullet sponging and totally unbalanced combat, youd either be a god that couldnt die or someone who has to land 50 headshots with a sniper rifle to kill someone
This. I rarely if ever saw a bug, even on release.
My gripes with the game had more to do with the features we were missing: a metro system, character customisation (hair stylist, tattoo artists, visible cyberware modification, cyberpsychosis, car customisation...), a gang reputation system, meaningful lifepath repercussions, like being able to join a gang as a streetkid, or own a cool car/apartment as corpo, or have your own custom tricked out car as a nomad...
The game feels much better than it did - driving was not great at release, and the perks you unlock now actually feel impactful and meaningful, but I still would have liked some of those features included.
I had a few glitches. Like grabbing onto a ladder and being thrown into the air. Or falling through a road once or twice. But that was the literal release version and still happened rarely. Performance was pretty bad with the first release imo but playable enough.
