Yeah...I think I remember that thing.
On black friday I was in best buy digging through the 360 discount bin. 2 women who were shopping for their kids were in the same area. One of them saw sonic unleashed and picked it up and said "Oh, I didn't know Sonic was on xbox." They were trying to choose between it and a wii game, I think it was black knight.
One of them said "I thought Sonic was only on Nintendo." The other than argued that all game companies make games for all systems now...yeah okay. Well then the first woman said "Yeah but Sonic is nintendo and nintendo doesn't do that."
Now I try to avoid contact with strangers most any given time, but I just couldn't keep my mouth shut any longer. I looked up and said "Sonic isn't nintendo, it's Sega." They just looked at me puzzled. I then told them that he's been on most every console since sega's dreamcast when they bowed out of console making. Again, blank stares. So then I said "Remember Sega Genesis? He started on Sega Genesis." Finally the first woman said "Oh yeah, I think I remember that thing."
It was sad that people (even the general public) think Sonic is a nintedo creation, but at least random middle aged mothers still remember Sega Genesis. Just goes to show that genesis still has more brand recognition than sega in general with most consumers I suppose.
