I think everyone knows the whole Zoo thing, and it shouldn't be surprising that they're going to keep releasing games. This game has a market, and there's a good chance some casual people will enjoy it, especially young people who are enthusiastic about gymnastics (although they're probably not focused on video games). Either way, these companies that crank out games do have the rare occasional merit.
Majesco was the only reason that Psychonauts was released, after Microsoft dropped support, and that game is amazing. Otherwise Majesco releases a lot of garbage, more than good games. Recently, Destineer (I swear it's the same company as Zoo, but with a different name so they can release even more games, like how Konami created Ultra back in the NES days), released Dragon's Lair Trilogy. While some might not like DLT, I really appreciate it, and no other developer would pick it up.
My point is that all these companies like Zoo have their place, and can easily be ignored by gamers alike. The only reason I'm aware of these companies, and their games, is because I pirate games. Chances are if you didn't visit gbatemp regularly, or follow the scene, you wouldn't even know these games exist.
