Colorful. Also a bit foolish to assume Hayashi is solely responsible for the bad things in their games or the good. This isn't directed solely at you, just to be clear.
I believe the last time Hayashi actually had a large impact on a game was the AI programming for NGB...and that turned out alright. It's a team effort and whether he's the public face or not, he's not a punching bag. I've met the guy in person and, as much as it seems like a funny coincidence with when he took over and the games that we've seen, he came off as a nice, focused guy that just wants to make games people like.
NG3 didn't turn out too well. DoA5 had some major issues at launch. But, unlike before, the games are publicly shown off and playable pre-release, patches and updates are released that factor in player feedback, and there's a genuine show of support from the developer for the DoA scene and for the NG playerbase. I'm inclined to believe that the team got new leadership in the form of Hayashi, went a different way with some games to try something new, and then were a little shocked by the response and quickly worked to make it up to those of us that were unhappy.
I don't know about you but I'm not looking for someone to blame anymore after the DoA5 patch, tournament support, Vita releases, and now Razor's Edge for PS3/360. I'm looking for someone to shake hands with and that's precisely what I'll be doing in a couple weeks at Final Round since Tom Lee will be there supporting DoA. They have our backs so I think it's time to stop looking back so damn much. Your call, though.
