I feel like he just wanted to stop directing. Looking through the development of Killer7, Mikami himself forced Suda to write 100% of the game's scenario and he was kinda unconfortable in doing that (even though he did write the whole plot).
I feel like No More Heroes 2, Killer Is Dead and maybe even Lolipop Chainsaw, which is my favorite non SUDA Grasshopper game (still haven'played Contact though), were attempts in passing his title to his co-workers so that he can focus on being a CEO.
When i think about it, the only major stuff he did between Travis Strikes Again and No More Heroes was Liberation Maiden (which is pretty underrated and i would recommend it anytime if you like arcade stuff). He was stepping away from his director's chair and even Killer Is Dead, which is a throwback to the old Kill The Past games, wasn't really a Suda game when you think about it.
So, i wouldn't call him a hack. I think that, since he directs since the PS1 era, he just wanted to focus in growing Grasshopper as the administrator, not as a dev.
NMH may be more lighthearted, but it's themes were really consistent. It was a pretty good and blod parody of action games and the overall industry. It had this kind of geniality and eccentric choices which i feel that most later Grasshopper games lack.
About Let It Die: it was directed by the same guy that did Killer Is Dead. Not really a very Suda game and some of it's problems are similar to Killer Is Dead's. Lack of interesting themes, repetitiveness… It's a charmy game and i liked it, but sure has lots of wasted potential.
About TSA: i think it's a game made for the Grasshopper fans and the marketing was done wrong. I know the development originally was meant to be a No More Heroes and Devolver crossover but it really derailed because of budget issues. But the problem is: the marketing was done thinking about this concept, not about what the game really is about.Post too long. Click here to view the full text.
