Long story short, Nord 1 was a very buggy mess on release, was short, was hyped up by Ahri to have lots of innovative gameplay elements (which fairness to him, it did, but like half the game didn't work on release), and as a result, lots of people were really pissed about its quality (especially since he was pricing it somewhat high for what it was). Ahri apologized, put a LOT of time into fixing things, adding new art and scenarios, and adding even more gameplay stuff and hyping it up on his dev blog, which resulted in Nord 2. AGAIN, the release was extremely buggy/unplayable, and from what I read on earlier threads, DLSite actually got so many complaints and negative feedback on Nord 2, that Ahriman had to pull the game from the site temporarily, issue refunds, and apologize profusely on basically every platform he pushed the game. Fast forward (2-5 months? I'm not too sure on this one), and he is finally able to re-release the Nord games in their playable state (which I assume is what most people on this or any thread have played), but as a result, this whole scenario has left a sour taste for a lot of his followers.
I think its totally fine to push the envelope and innovate on gameplay (and to a large degree, he's quite successful on that front; most of us really like his kind of game because its unique and to their tastes), but when that comes at the cost of unstable systems, horrendous releases and super lengthy delays, it turns people off. If he gets Eldritch Detective Misogi right, it'll be the next Asagi. But, having followed his dev blog and his constant talk of major problems with his rehauling of the gameplay system that hes running into which is causing the delays, I get Nord flashbacks (esp since I think there's nothing wrong/bad about the current demo gameplay). And its extra bad because I think a lot of his fans (myself included) think his simpler executions of gameplay have been good enough (like Asagi, or the current running version of the Misogi demo), and that all that's needed to tie it together and satisfy is lots of great art/CGs and a decent-ish story. I'm worried he's trying too hard to make his gameplay system novel, and that its going to blow up in his face as it has before.
