In general, for the most part, NISA does some very good voice casting for their games. Makai Kingdom was an especially good case in terms of casting, especially for Overlord Zetta-- it's just a shame they couldn't keep Crispin Freeman in future games, but the voice actor industry, especially in the west, is a whooole other mess that one doesn't need to get into.
... also I didn't mind Gordon's voice in Disgaea 1... But he was meant to be a loud ham regardless, evokative of the older space action shows/tropes, so his voice fit well with what they were going for. Kinda like how Mao's nasally nerdy voice in English fit a lot better to me than his Japanese voice. Shoot, I'm willing to say I actually prefer the English VAs when it comes to NIS game-- a lot more feeling and emotion seems to go behind them. long as we're not talking about the extra chapters in Disgaea 3 Vita. uggh. UGGGHH...
