While the Super Robot Taisen fan community is usually starved for any English release of virtually any game in the series, even a weirdo spinoff like this, Super Robot Taisen OG Saga: Endless Frontier has seen a mixed reaction from fans who are usually diehards. The issue at hand is that, contrary to fan expectations, there is absolutely no English voice acting in Atlus's version of the game. Whenever the character speak during combat or occasionally during cutscenes, the original Japanese voices were left in.
Why would a publisher known primarily for its high-quality localizations just not change the voice acting in a game? Fans are speculating about laziness and cheapness, but they're basically wrong. I went to source and asked Atlus's Aram Jabbari why the game had no English voice acting. Here's what he had to say:
We fully explored recording English battle voices, but due to technical issues relating to the complexity of the game's sound design, we were unable to complete our dub. This outcome was much easier to accept in view of the excellent quality of the original Japanese voice work, and we hope fans enjoy the final product.
Now, if this surprises you, it shouldn't. Remember that the Nintendo DS is still a cartridge-based system (even if it's using flash carts). The average DS game is at most 256MB in size and most are one heck of a lot smaller than that. For games featuring voice acting, the voice data is usually highly compressed and sometimes fragmented in order to save space. Endless Frotnier features tons of voice acting (by DS standards), so I imagine the voice data was stored in elaborately strange fashion.
Basically, while it's pretty easy to swap out Japanese for English voices on disc-based media, for a cart-based game it can be really difficult. Whether Atlus just couldn't figure out how with Endless Frontier or decided it wasn't worth the effort, I'd just be happy the game got release at all. Remember that back in the bad old days of localization, an issue with voice data like this probably would've killed the game outright.
