Got it on sale a few weeks ago, beat it about one week ago. Linux PC, decent hardware.
Maybe 3-5 bugs, mostly small stuff. Only saw 1 dude randomly t-pose, and another (a civilian hiding from a shootout) slowly fade/sink into the earth. Maybe one hard crash, which isn't bad compared to the issues I'd see with FNV or Skyrim. In other words, played fine.
Cool setting, and the first half of the game is amazing -- blew me away -- but the gameplay is fairly repetitive otherwise; i.e. go here, kill people, collect loot, go here kill people, collect loot, go here don't kill people (stealth mission!), but then get in a shoot-out after you steal the thing and collect loot, etc.
Skyrim and FNV felt like you had more choices as to how you played, while GTA V had a lot more to do, like the silly Yoga minigames, or stock manipulation, or submarines and aircraft, etc. I played a bit of Shadowrun and CP2020 on the tabletop and I remember the old CP2020 Rulebook talking about "style over substance" and that's kinda how the game plays.
I'd grumble if I had paid full-price but am pretty satisfied at half, and I'd consider the DLC as long as it wasn't buggy as hell and got alright reviews.
