GTA is GTA because Rockstar perfected the formula and the engine over several iterations of the game. I'm sure every GTA is a mountain of work to create, but its a considerably smaller mountain than starting from scratch.
But putting GTA aside, I don't think CDPR ever promised to create a Cyberpunk-GTA clone.
There's a lot of small bugs. It doesn't run particularly well, but I'll say it again - the core game is fun and story well written. I'm taking a break, but I look forward to revisiting after the first few big patches.
Edit: One thing that's always worked for me is to amortize the cost of purchase by time played. If I get only six hours of Cyberpunk 2077 played at $60. That's 10/hr for entertainment... which is better than a lot of stuff.
I'll probably sink 50 or 60 hours into the game completing the main story. That's $1/hr of entertainment... ridiculously good value.
Gamers are so cranky.
