Four characters. Grids. Real-time combat. Dungeons. Puzzles.
I think most people here played, or at least own, the original that came out back in 2012. That will give you a pretty good idea of what to expect in the sequel, because the core of the game hasn't really changed very much. However, just about everything else has. Rather than being confined to similar dungeon corridors filled with traps, puzzles, and monsters, the party is shipwrecked on a mysterious island that at times seems like it was ripped right out of the Myst series. Through nearly two hours, I've spent more time outside [on and around a beach and then inside a forest] than I have in underground dungeons, which gives the game a better sense of discovery and exploration. There's also more and a greater variety of puzzles, which lead to new locations and chests full of loot.
I'll admit that although I did like the original, spending all my time crawling through a dark dungeon ultimately didn't appeal to me all that much. The sequel rectifies that so far I've enjoyed it far more than I did the original. It's definitely worth getting.
