A stellar game bogged down by over promises in marketing. It's a fantastic game and I played it at launch, 100%ing it with a total number of bugs under the number of fingers (both hands!). When it tried, it has some of the coolest cyberpunk concepts I've seen, not even in the main quest.
For me I think the saddest part about the game is how modding brought some of the lost vertical slice content back to the game and how some of the early game content fades throughout the game. All the passenger seat riding is quest-only, by the end of the game you can only be the driver. Wall climbing wasn't critical, but it was a very popular part of the E3 showing.
Overall though it's still la solid gamem I'm glad that mods brought in a metro system and Spider-Man swinging and pole vaulting :D
