For me this news hits me in a personal level because if I'm not mistaken, he was one of the people who ensured that sound cues were added to Injustice for interactibles. And also, as everyone knows he was a huge supporter of the tournament scene.
This is sad news indeed. Still though, I wish hecterrific success in anything he chooses to venture into.
That's a bummer, he was my favorite and seemed to be the only person with some power that really gave a shit about the NRS game's balance. Can't say I'd blame him though, NRS puts out a game, we all have fun, then find bugs, see how broken some stuff is that won't get patched/changed and complain non stop. The cycle will only continue.
Moving on to bigger and better opportunities is a great thing for Hec and I wish him all the best. Hector is one person I'd describe as "a true professional" -- patient, thoughtful in what he does, keeping a steady hand with the people around him and displaying leadership without excessive bravado or ego.
NRS was fortunate to have him, and wherever you land next Hec, they'll be lucky to have you there too.
