What about it is the most ambitious?
Btw FS2020 came out this year, certainly that's the most ambitious we've ever seen.
If anything it feels more like the game is getting a pass (like FS2020 got) since it will get better or they expect the day one patch to fix most issues.
I think he means it is CD Projekt's most ambitious project to date. It was such an ambitious project for them that they had to double their dev team size compared to Witcher 3, and give it a year more development than Witcher 3 got.
Sure, however I doubt there are many studios that take on a less ambitious project as there next big title ;)
Anyway I read some of the lower scoring reviews (usually way more informative than the 100s) and besides the bugs the theme seems to be, lack of emergent game play, most of the world feels like superficial set dressing, nothing new (a combination of the all the best things from previous games which is always good of course), no real freedom to approach things differently or rather it doesn't matter all that much how you progress you character.
The strengths are the side quests, characters and general world building. As long as you follow the path set out by CDPR you will have a great time. However there is not much point to explore on your own or try out different things. So in the end, quite a linear rpg.
Eurogamer's early impressions also are a bit on the low side (after 40 hours of playing) mainly to do with the balance (which can be fixed)
The biggest shame there, so far, is that so much is locked away so deep in the skill trees. The worry is that you'll get too far through the story to fully enjoy even a narrow, specialised slice of what Cyberpunk offers, let alone the whole thing. For now, combat feels limited. The guns are serviceable, and melee is fun in a slightly sickening way, but very simple - think The Elder Scrolls, but even simpler: a weapon in just the one hand. The sense is I'm a good way into Cyberpunk 2077 but still waiting for its systems to really open up.
I'd say between the 30-hour and 40-hour mark is where it gets going, weirdly enough. I've already played a fair bit more since writing this - it takes a long time to earn the XP and $ you need to actually explore the game's systems, and I think they got the balance slightly wrong there to be honest, but more on that in the final review (probably).
That's a long time to get going, at least it's a lengthy game!
