The Witcher is a series where the developers learnt from the mistakes of the previous 2 and made a gem among rpgs worthy of the time invested into it. Witcher 3 features interesting characters, a world that seems realistic enough without going overboard with the dark/brooding themes that plagued the previous two but also a story and an open world them that really fleshes it out. A great plus is that it has a very good performance even on average systems which gives it great value. Highly recommended even if like me you hated the first and found the second good only for its story, it will change your mind for sure.
Blackguards as a whole is a well made game but with major issues that can make it very boring down the road. Story wise it is acceptable, the main story is cliche but not in a bad way and there are a lot of side quests which even though they don't affect anything in the world, apart from gaining xp/gold/items, help to flesh out the world that the game is established as well as the characters. Without giving any major spoiler, only major complaint is that the game throws a couple curve balls which leads you to lose characters you have invested in without any prior warning or indication, which happens in major plot turns. Graphics are well made and attack/magic animations well done but again the downside is that the non combat areas are basically static images and the equivalent of facebook games as far as how you interact with other characters. Other than that the game is composed of a series of battles in a hex shaped grid and follows a dnd style of approach of both levelling up and fighting. There can be a high degree of strategy involved which is refreshing, and your characters will be challenged all the way to the end. Basically very rarely you can just rush the enemy and most battlefields will have some kind of gimmick to exploit or be mindful of. That also makes the battles a little slower than most other games. The downside is that there is also a big luck factor involved since most actions are based on chance. Overall it is a good game if you like a string of combat encounters tied together by an average plot and character development and put together into a decent combat engine.
