And it'll probably turn out fine. I really don't understand why people are panicking because it's Ubisoft Osaka. It's not like they're a bad development team for making a bunch of Petz games, they're just workhorses given what the company calls for. People get snooty about developer pedigree, but it's the 1% of working, professional game developers who can choose their projects and make what they want. Most are your regular jobber team trying to make something worthwhile within the schedule and budget they have, and Ubisoft's got a million of these kinds of teams. (These Ubi teams BTW have a history of being pretty solid as far as B-grade work goes. It's rarely anything special, but even going back to GBC projects, I can't think of too many bargain-bin Ubisoft internal team projects that have been outright turds.)
I mean, maybe there are Gravity Falls fans actually suspecting something ace-caliber here, but to me this is exactly the type of who-cares license (maybe the show's good, but the brand means nothing to games yet) that you give to a perky team looking to break out a little and put an engine through some unexpected paces.
I'm not sure why Rayman Origins 3DS went bad or why Ubisoft pulled UbiArt projects from 3DS for so long (even if it were just its licensed stuff, the engine at least looks nice on it, and maybe if a game were made custom for 3DS it would have fewer technical hitches?,) but I'm hopeful that this bodes well for Ubi's relationship with the platform.
