The issue is, the people defending it and saying "there is plenty to do" are technically right. The problem is, most of the "to do" is to sneak/break in somewhere and either kill/knock out enemies, rescue someone or get a package. And while the stories surrounding those missions are well done (as always by CDPR), there is not enough non-combat stuff to do where you can interact with the city and its NPCs. With the world really.
And this is really where you see that CDPR zoned in on the story and only the story. Its the one thing they do well (at least the moment-to-moment storytelling, one could argue about some points in TW3s main story, but thats not the topic here) and they didn't venture outside of that. Which imo is just a big mistake.
They need to do some soul searching imo. Yes, a good story is the backbone of every game like this. But. I hope they will add a lot more ineteractive features, non-combat activities and also make the random NPCs, traffic, vendors and police "smarter" and more responsive, so that in the end those aspects of the world will be fleshed out too and we will have an immersive experience on all levels.
(Also, not the topic here, but pls overhaul the loot system, in its current state its just too much loot with too little value and not enough focus on the style/fashion that was advertised)
