Would Ouya constitute as a platform or a concept? I'm actually very surprised that it's not already on here in some fashion. Since there are exclusives planned, it would be a platform unto itself, right? Has it not shown up because there are still people convinced that it's a scam?
What about cell phone games that existed prior to smart phones? Most sites have a generic "Mobile" category, or at least acknowledge BlackBerry devices (which are still widely available with new releases, even if they're not as prominent as other mobile platforms. BB10 comes out in January 2013). These phones have both the ports you'd expect as well as plenty of exclusives, not to mention many games that started on other mobiles and have come to more modern platforms.
Also, since every platform these days has its own shop, I'm also surprised that a Wii U Shop isn't a platform yet. There are definitely some games that are exclusive for download as well as retail games being given that option. I mean, if PS3, PSP, and Vita get their own shops and they're loosely tethered, not to mention DSiWare/3DSWare.
No skin off my nose if these are rejected, but I figure it wouldn't hurt to ask.
Thanks for your consideration, mates.
