My favourite game. I enjoy this more than I did The Witcher 3 (not including DLC). It can be a bit buggy but as long as you save regularly then it's nothing to get annoyed about. The characters are fantastic! Red, Lohse, Fane are all spectacular characters with amazing stories which is why they're my favourites.
The combat is intuitive and fun; I have rarely gotten bored of it. Just as a tip though: craft items and spells - it makes the game so much more interesting. And go builds that are fun and unique, don't just research the most OP build and use that. It's boring and takes the personal feel away from the game.
