I know I'm late to the party and what I have to say has probably said before, but I have a LOT to say about the story and some about the overall experience and gameplay.
To start, I really loved the overall game at how much love and care went into the world, the characters, the story and level of detail in Enderal. The voice acting was superb, which was especially impressive considering that Nehrim was all German. It blows my mind how something that is free can come so close to the quality of the base game.
At first I didn't really like the change to the levelling system, since the Skyrim system was already so good that I had to wonder - why change it at all? The memories were also just the levelling screen placed in an alternate reality room, so that wasn't really any different in practice. Though I do admit that it kept me strapped for cash especially toward the end game which I was grateful for in the end.
The story, until the very end, was wonderful. The more active companions in which what you said to them mattered was great and better than anything Vanilla Skyrim could pull off. I was literally in shock and heartbroken at the outcome of what I experienced when I finished the quest with Ryneus - something the vanilla game could never do.
Unfortunately, the ending completely fails at giving me the same level of emotional investment. In fact, it takes everything I had ever had any sort of investment in during the game and tosses it out the window. The only real choice I have in the end is whether everyone dies on a continent or whether everyone dies in the entire world.
Either choice is an atrocity to me, but given the way the story goes, suffice it to say there's no way to prevent the Cleansing. But if something so fundamentally disgusting and against my principles HAS to happen, I have to know WHY. But I don't. I never find out anything about the cleansing as to WHY it happens. This is what the story is missing - justifying its ending even if its overly depressing and negative.
Another huge problem with the ending is something so basic it frustrates me to no end - SHOW don't TELL. I don't want to hear in my ending that Qyra may have constructed their beacon and may have banished the high ones in a few sentences. I want to see the effects of my sacrifice, to see the effect the Cleansing had on Enderal but with the hope of rebuilding in the aftermath. I want to see Calia lamenting my death, not saying that she will. Instead of the cutscene with the Guardian, the effort there should have gone into a cutscene showing the aftermath regarding everything (or as much as possible) that I had gotten invested in.
And even then - why should these two endings be the only endings? Throughout much of the endgame a goal to stop the cleansing is simple: stop Tealor. It would have been simple to implement a way to reach the temple before he activates it, and then emotional investment might have actually had an impact: being forced to kill Tealor in front of the entire order to save them. Since you're given a teleport scroll when Calia/Jespar comes to the Guardian and finds you, whether or not you could reach Tealor in time to stop the Beacon could have been tied to your relationship values, since Calia/Jespar might not come to give you the scroll if you're relationship values weren't high enough. The fact that the game itself teases this solution for the length it does makes me think either that they didn't have enough time to implement it or that the writers wanted to force their depressing ending on the player.
(sigh) While the ending in terms of companions was far better than Nehrim's, overall the main story suffered terribly from these shortcomings. Apart from Kim, the Nehrim main story had a much more solid ending overall. Next time SureAI, make sure both the character and main story endings both come together in a way that a satisfying ending should at least be POSSIBLE.
