Divinity: Original Sin EE - Dunamis (standalone campaign, played in SP mode)
Another well-made custom adventure for D:OS (one of only two I could find). I had a bit of trouble getting into this at first, because the beginning can be quite hard, even in Classic Mode. One of the reasons for that is that it takes different approaches than the main game, it's more in the spirit of Baldur's Gate, in that you only have one main character, and if that one dies, the game is over, even if companions would still be able to raise that character. Add to this that enemies can kill you with 2-3 hits at the start, and you only have the three skills you pick during character creation, so not a lot of tactical options yet - but your choice here can make all the difference between challenging and frustrating. On top of that, you start with only one companion, and while there are three in the game, you are limited to two, and all of them are built a bit subpar, IMO, with skill combinations that aren't great. So at first, you're really better off trying to avoid combat until you have more companions and can afford to give them some more skills. The major part of the module is an open map with lots of smaller quests revolving around a town, and the couple of fights there are on this map felt a bit like a puzzle - scout the area for dangerous encounters, make a note of what level the opponents are and what threat they pose, then figure out the best order to tackle them. A bit like Gothic.
And like Gothic, it also has a day and night cycle, which can be a bit annoying and helpful at the same time. Helpful because you can always find all important NPCs in the common bedrooms at night and still talk and trade with them, annoying because it might interrupt what you were planning to do - sometimes NPCs walk away to their homes even in the midst of a conversation. Occasionally, some scenes would not trigger, because they came with a slight delay and I had already clicked on something else in the meantime. But in these cases, reloading and being more patient always worked. And sometimes the trading did not work correctly, but the author warned about that, so I always saved before trading, and when something went wrong, I reloaded and tried again, with success. There were occasional typos and such, but it was not too distracting. Most of the text was fine and able to convey the story in an immersive way.
There is quite a bit of Choice and Consequence in this module, too, although it is not all that obvious; I think many of the choices are about completing the available quests or not (or rather which ones), and most of the consequences only become apparent in the epilogue. This module also took about 10 hours to complete, though part of that was running to and fro looking for things to do. It only goes up to level 5 (or 6 with the last battle), so you won't be able to use most Adept skills yet. All in all, I liked the Necromancer adventure reviewed above a little better, but it's mostly a matter of preferences, and this was a nicely crafted and enjoyable bonus story, too.
