First playthough complete. Overall I enjoyed it. Story was good, if slipping in its narrative here and there, but the ending really didn't do enough to explain the whole twists and what not. Maybe these are explained further in Ending B, which I'll be going for, but they probably should have dedicated more time to fleshing things out.
The game had a lot of rough edges and flaws, but I still really enjoyed it. I really liked the bullet hell style of many boss fights and enemies, I liked the pure action combat, and I liked how the game would mix up its style in homage to many other games.
Some parts were pretty bad though. The boss fights at the junk heap were great, but everything else about those parts of the game was absolutely terrible. The machines were a pain in the arse to fight and no fun at all.
My biggest complaint, without a doubt, has to be the sidequests. The banter between Nier and Weiss were the only good parts, outside of the occasionally interesting story. As it stands though, 90% of the sidequests devolved into nothing more than utterly abysmal fetch quests. They were so bad I literally cannot think of another RPG I've played in years that had sidequests this bad. Nier would have been a better game had the sidequests been removed entirely and instead had their development time put towards other things, or the plethora of sidequests refined down into a meer few with richer content and variety.
As a whole though I felt Nier, and I said this earlier, has a lot in common with much of what I love about Grasshopper's games. Both them and Nier have this remarkable self-awareness in their execution and style that they seem more focused on introducing new and varied ideas and mechanics over maticulously polishing singular ones. A lot of what I loved about No More Heroes I felt was present in Nier, particularly perspective shifts and crazy boss fights.
Assuming its not overly difficult I will be going for all four endings, if just to 'finish' the game in its entirety.
