Cool idea for a thread!
I won't do Capcom because it's so obvious.
1) Loved SEGA gaming company because of Sonic.
2) Then they created Sonic 06' and many numerous other Sonic based failures (Sonic Boom, Sonic & Secret Rings...the list goes on n' on)
3) I just hope Sega finds a way to make Sonic not suck anymore. It seems so easy to create a good game with a well known IP yet they fail every time.
