If you liked the first two games you are probably not going to like the third. It is a straight dungeon crawler without story but rather small extra lore bits about the world it is taking place in. I jumped straight to Trails of Cold steel. The crossbell series would have been in between the two but an english version is not due until fall 2022.
Too many complicated aspects to learn and bad UI. Almost the fact that you can only scroll map with middle mouse roll button made me close down the game. And when I got smashed in the first fight I realised that this game is a massive investment in mechanics you wont get any real guidance in. Please try a demo before shelling out the bucks for this game.
Although the game is set in an interesting environment I quickly lost interest. For an ARPG it is very dull, you engage group after group with the same monsters and use the same hit and run tactics. The story is mostly an excuse for travelling from A to B, then from B to C and so on. The game is somewhat difficult but that just adds to feeling of a chore. Graphic and effects are old and not so eye pleasing even if they aren´t ugly. This game done right is another game that is available on GOG, the Van Helsing Final Cut. That is a true gem whilst being very similiar to Titan Quest. Grim Dawn is another alternative even if not as good as Van Helsing. I would only recommend this game to someone who likes a slow paced ARPG set in a different environment and likes to fight similiar mobs in large areas (that aren´t really worth exploring). The character progression mostly add small bonuses to existing stats which is a bit underwhelming.
