Are there still bugs? Yes. Loot items that you can't pick up. NPCs popping in or failing to move their mouth welhen talking in a cutscene.
I'm near the end, and none of the bugs I encountered were of the "I can't complete this quest" or were otherwise terrible.
8/10. Loses points for bugs, main storyline that was far too short, things that aren't bugs but doubt work well (minimap) and just not being innovative. This would've been a great game 5 years ago, but now? Not really.
Nice graphics, good stories and characters. Mediocre driving and shooting mechanics. Worth it on sale.
