I didn’t have any gamebreaking bugs, but had soooo so many “how the fuck did this pass quality control?” bugs. Most of them were pretty funny, like the time I didn’t understand how the cyberpsycho quests worked, and tried to take the unconscious body with me.
The game system did not like having that body in the trunk of my car, with hilarious Dali-esque consequences.
Aside from that, the deep systems that were promised were extremely shallow; the onscreen map was fucked, too small to see turns coming (pathing too CPU-intensive when zoomed out?); the onscreen HUD still last time I played was too small to read on a 4k screen; the car handling / driving is still atrocious (at least, last time I played). It is a fun game, especially for those picking it up now. Mods make it much more fun.
