Gaming is about choice so sandbox is not the wrong approach, specially for cyberpunk where it really is just about night city in and out (well there's other stuff in the genre but the tabletop really is just night city), just be smart about where you allocate your resources (pro-tip: it ain't graphics you cowadoodle brogamers). I had more fun with ascii games than current year slop, it really says something about our gaming societeh. At least indies know better than to just go for a pretty packaging with nothing in it (but I bet you give em triple A budget and they spend 10 years putting pretty pixels, half their budget in marketing and 3 days with the actual gameplay, never fails).
