1. Witcher 2 - this is overall CDPR's best game. Especially as an RPG with meaningful choices. I mean, this is a game where depending on a single choice in Act 1, the rest of the game is entirely different, and you really do need to replay the game to find all the answers to all the various plot points. There are just so many different outcomes depending on choices. It's a masterfully told political intrigue story, which depending on your play-through, could have a very different appearance depending on what you know and don't know. Let down mostly by some clunky gameplay/control mechanics and a lack of actual monster hunting. Roache is an absolute bro too, quite possibly one of their best ever written characters.
2. Witcher 3 - the best open-world RPG I have ever played, with side-quests, which while repetitive in terms of mechanics, were often extremely well-written little stories, and a game world that felt full but also realistically crafted. The overall story, while nowhere near as interesting or in-depth compared to Witcher 2, is a wonderful culmination of the journey for the characters which players came to love over the three games. By far the best gameplay mechanics as well of the three games, I found it a good mix of challenge and accessibility. I actually don't get bored playing it. Also has absolute top-tier expansion packs, both are absurdly good.
3. Cyberpunk 2077 - the world crafting is stunning, and for me at least the gameplay loop is fun, although with some major balance issues (leveling is too easy, as is street cred). It's storytelling is far more theme based, as opposed to character based in the Witcher, and for me personally, while it is still excellent story-telling, it lacks something. I think this is why many CP2077 players complain that V is an empty slate, and that many of the characters are a bit too one-dimensional. With Witcher, they had existing characters to built on, and who you go on these amazing journeys with them in which they grow and interact with one another. Whereas with CP, it feels more that they had certain themes that they wanted to focus on in the stories (as opposed to characters who go on a journey) and so the characters became almost like vehicles for the themes. The story beats leave you thinking deeply about complex topics, but compared to the Witcher, I just felt more disconnected from everything.
4. Witcher 1 - I only played the Enhanced Edition, not knowing anything about the IP but looking for cheap RPGs to play, I picked it up on a whim. Story-telling, world building was all amazing, but the engine showed its limits (even in some of the quests they tried to do) and most of the gameplay mechanics are annoying (loading screens on every damned building, the zero-thinking combat - basically just group style into win, and by far the worst inventory of all their games). I actually gave up on the first playthrough right before the final part of the game because the mechanics drove me up the wall, and I only went back to finish it right before Witcher 2 came out.
Not played Thronebreaker or the proper Gwent, although if the latter built properly on the version in Witcher 3, I'd probably love it.
