I'd actually say the OP was true for me. I got burned by Mario & Sonic, Metroid Prime 3, Super Paper Mario, Zack & Wiki, Twilight Princess Wii Fit and Wii Music. I was also a little disappointed by The Conduit.
Apparently the only franchises I can trust now are mainline Mario games. My favourite home console series are Mario, Metroid, and Paper Mario but two are uncertain now.
