Sure, poop and fart jokes did wonders for the Lunar series. Not to mention Austin Powers references. If that kind of shit is needed to make a game interesting, then what you have is a lousy game in the first place, or at least, a boring story. You can liven up dialogue without dumbing it down.
Exile was tweaked to be too easy, and they made the sequel (Exile: Dark Phenomenon) hard to the point of near-impossibility. I don't doubt they screwed up elsewhere. And Vic Ireland was/is a pompous asshole.
If it comes down to a bad translation or no translation, I'd pick no translation. Then, there's still a chance a decent company might license the title.
Kind of like how it says in a review of the Sega CD Popful Mail at
http://hg101.classicgaming.gamespy.com/popfulmail/popfulmail.htm "While a lot of people don't care for their loose interpretations of the original Japanese version, a lot of the dialogue and extra gags that they added really fit the game. In a part where you come across two soldiers, whom were just regular boring characters in the Japanese version, they toss in a Dragnet reference." Yeah there were some juvenile jokes in their translations (although I usually found them funny) not all the jokes/extra stuff they put in the translations were like that.
And I never said their extra jokes made the games interesting, I said they made the games
more interesting.
Even if they messed up bad with Exile 2, I don't think the changes they made to the other games were game-breaking changes, just annoying ones.
And for most of the games that Working Designs released, games that fit into a niche category (very anime/rpg) that isn't the most popular type of game in the US, I'd pick a bad translation than no translation since the chance would be slim that some one else would publish it for the US. There are so many decent/good JRPGs that never made it to the US since the market isn't big enough to bring them over. If it weren't for Working Designs we probably wouldn't have gotten Vay, Popful Mail, the Sega CD Lunars, Alundra, Growlancer 2 and 3, Exile, Albert Odyssey, Dragon Force, Magic Knight Rayearth, Vanguard Bandits, and the Arc the Lad collection.
