50% off on PC and still feels expensive
I don't want to sound like CDPR defense force here, but it depends on how you'll play it.
I'm looking at taking another run through and will probably just focus on the main quest to unlock a couple of trophies I missed last time around. It'll probably take between 5 - 10 hours to get through and that would probably represent poor value for money if that's all I ever did.
My first run, though, clocked up over 100 hours as I experimented with crafting, went after owning all the cars, completed all side gigs and police encounters and also spent a while reading shards that I picked up. I really enjoyed the world it was set in and easily got what I would consider value for money. I actually spent 90 minutes sprinting and jumping through the wastelands and santa domingo just to up my athletics score because I needed a perk point. Even whilst doing this, I was still discovering little secrets, fragments of lore and an iconic weapon that I would have otherwise missed.
tl;dr - just like every other RPG, it's exceptional value for money if you're interested in immersing yourself within the game world and participate in every activity it offers.
