Would you purchase a game that used mouse/keyboard controls as a primary input?

There was also a SEGA Genesis mouse but I'm unsure what for

I actually have that mouse, but I've never used it. Gamester81 just posted a review of it a couple of days ago, though he focuses mostly on Wacky Worlds.

I've never used the mouse, though I might try it if I ever try a game like Eye of the Beholder (which I believe supported it).
