Sega did shit, they stole that rod from the arcades... it will be some bankrupt company that made all this shit originally.
The only thing sega invented on the dreamcast was that shitty VDU memory card, that slot into the pad like on the n64.
Sonic is for kids anyway, ironically he was billed as the "mature mario":

Remembering back to the launch of sonic i find that rather amusing
On a more serious note, why do people like sega so much the vast majority of their catalogue is utter, utter tripe? I've never understood it. Very poor arcadey gameplay for most of their games, imo the sole reason they flopped badly out of the hardware business was their ultra-shitty software, not their very competant hardware. Didn't have the money to buy development studios like sony and xbox, and didn't have the talent that nintendo had/has to get people to invest for their inhouse software. Their hardware was normally half decent though, that's for sure
If you search the american patents, nintendo has a motion controller registered back in the 80s

They got some crazy shit too, and a "phoneboy" (mobile phone + gameboy), most of which never materialised
Nintendo r0x0rz sega in this arguement though, they've systematically even invented or popularised in a major console:
dpad (i)
shoulder buttons (i)
analogue controls in 3d games (wtf sony?) (p)
rumble (p)
Gameplay:
Platformer (i)
Action Adventure (i)
Topdown RPG/Adventure (i/p)
Equal hardware 'innovation' (if it isn't as mass market appeal) and more importantly, software 'innovation'/polish; its the reason they are still around. I bet if nintendo made the dreamcast it wouldn't have been a flop, exactly the same hardware but different software would have made the difference.

Hardware:
VDU (i)

A retarded hedgehog (i)
Honestly, sega seem pretty limp these days and their cannon is shooting blanks

. That's not to say the dreamcast was bad in any way (its 90% of penny arcade's material

), but sega are imo... they've been pretty shoddy for well over a decade.
Few good games though, Soul Calib, virtual fighter, collect underpants, ,...., profit. If you like arcade games anyway
ps. all i got left is a game gear, the rest either crapped out, was never bought or was sold
