Growing up I was a huge fan of Mega Man and the Mario games but I wasn't really much of a sperg for any character in particular. Sonic was really more of what I'd play when I went over to my cousin's who had a Genesis instead of NES or SNES. I can't say I've played any Sonic games since the Genesis ones and really I don't have the desire to play any newer ones either.
It's interesting though, speaking of Mega Man, I was pretty upset at Capcom over Mega Man as time went on; I sort of felt like the series I loved was being both kind of ignored and being turned into something altogether different, it's also a bit annoying that x8 ended on a cliffhanger. I didn't talk about it much or get involved in some grand debate, but privately I had a little resentment at Capcom. Then when Mighty No. 9 was announced, I was pretty happy; I gave $50 to the kickstarter, told any friend I thought might be interested in it, and now that it's confirmed I couldn't be happier. I couldn't be angry over the story being different or the characters being changed - sure they added to the experience, but I'm mostly interested in the gameplay and I'm pretty sure most people would agree with me.
Sonic on the other hand from what little, I know has a convoluted story, an inconsistent play-style from game to game and isn't particularly appealing to a broad audience (again from what little I know). Chris, if anything, should be thankful his much loved series is getting something of a reboot when it's barely relevant at all, as many of us have said here.
