I've been playing Divinity: Original Sin 2 recently. The only problem I had with the first game was that it was difficult to get into the story-line right away, as the game sort of threw a soft intro at you with a tutorial dungeon. In the end, I loved D:OS and got crazily addicted to it, but it took about 2-3 hours before I started to get into it. D:OS2 has captured me immediately. The story starts off with a bang, and wastes no time in any kind of a soft tutorial type of dungeon like the first one did, instead letting the player learn on the fly from the pop-up help (which can be disabled when no longer needed). It retains all of the class/ability customization of the first game, and now some of the builds from the first game are actually even more viable, or viable much sooner than they used to be, allowing the scaling of power vs levels to be smoother. As an example, I'm playing an undead character, focused on fighting, geomancy (for poison spells), and necromancy, making him a stort of D&D Blackguard. Because he's undead, poison heals him inherently while hurting all the living enemies around him, and the more blood on the battlefield, the better, as he can also heal from that. In the first game, a build like that wouuld have taken over half the game to get rolling, as you'd need to find ways to get your poison resistance up above 100%.
So, I got addicted to that game right away, and since I'm in school right now for a STEM degree which requires a lot of studying, I've actually had to force myself to shelf the game until winter break, during which I will smash my way through it! I would recommend that game at full price ($45) for any Isometric RPG lovers, and would also recommend it to anyone that just likes fun stories and has lots of time on their hands.
