Yes you are. Just because you may have played 5 other games not in the Sonic franchise doesn't mean anything. Get yourself a couple emulators or something, or start looking at reviews of recent games if you're not into that idea. I'd recommend you a few but I have no idea what you'd like.
EDIT: So! I've got actual GOOD pics of my collection now. Here we are.

My systems..obviously. Yep, strictly Sega..sue me. My PC is what I use for anything non-Sega. Also that Game Gear obviously was preowned before me and doesn't work. Needs new capacitors. And sadly the Sega Master System and 32X are both absent

I'll eventually buy them though.

Controllers and such. I have another Saturn controller too but it's identical to the one in the picture.

Games games games. All 3 CD wallets are completely full. And all of the CD spindels are games as well, though there are a few software discs in there like Photoshop too. As you can see, I only actually collect legitimate cartridge based games. Can't be arsed to go out and look for legit disc based games for various reasons, sooo..mod chip ahoy! And of course DC and SCD both don't need one...oh and Shaq Fu was free. rofl.

And just for kicks this is what my desktop looks like at the moment.
So yeah my collection isn't that impressive compared to alot of people's but..I still love it.
