I wouldn't call it a phenomenon. I would just call it natural.
think of the wii and 360 with their ps2 ports. Examples of such being bully (360 and wii), and okami (wii).
think of the mgs series ports.
think of the gta series ports.
think of the ports from failed sega consoles.
think of ports of ps3 games on the 360. An example being virtua fighter 5.
etc....
