My old man is a theater director. He ran an outdoor production for our church during the summer for twenty years, and in that time it became a spectacle that drew tens of thousands of people every year. It became known for its brilliant use of fire, water, lighting, special effects, and battle scenes involving hundreds of people. During this time, my mother was also involved with it and created some absolutely brilliant costumes for the show that are talked about even today.
When they finally moved on, the project was given to the assistant director, "Roger". The first thing Roger did was remove all of the special effects, cut the battle scenes and replace it with some sort of awkward "dance" sequence using the same soundtrack, and replace all of the costumes with absolutely ridiculous third rate crap that didn't even resemble the time period. The audience numbers dropped to roughly 1/5th of the original attendance over the span of three years. It has never recovered.
Why did Roger do this? Because he was not interested in doing the church a service, and he was not interested in putting on a great show that people would enjoy. He wanted to make something that was his own vision, and he felt 100% entitled to do so. That meant getting rid of absolutely everything that had been conceived by my parents, because it threatened his own ego. His artistic vision took priority, and to hell with the consequences. This was his show now and he would do whatever the hell he pleased.
Well, the church didn't feel the same way. After a few years of that nonsense, he got fired.
If Hayashi had created his own studio, or developed his own original IP, I would have no problem with anything he did.
But you do not inherit a series with a reputation like NG's and do this to it. That is ethically wrong, plain and simple. I know exactly what Hayashi is doing right now, and it does not impress me. This is not a man incapable of creating a challenge, he designed the enemy AI for the original ninja gaiden on xbox. This is a man who is leaving it out very deliberately so he can make an artistic statement.
Same situation. Not impressed.
