Not really fair to nominate a sonic game and shovelware in general. I mean come on, does anyone actually expect sonic games to be good? That hasn't been the norm for some 15 years.
I nominate Destiny. Overhyped junk that just keeps pissing players off with each announcement,
Sonic Colors, especially Sonic Generations say hello! Also GBA Title"S" were definitely very underrated because it was on a Handheld. There is also Sonic AB2 that i think many loved (well i did at least >_<)
