If you were going for every variation on every console Madden might be up there:

You'd have to have all 140 versions to have a complete collection...

More if you want to include package variations and releases in other countries.

I think if you are just counting individual titles regardless of how many versions appear on multiple consoles, Star Wars is right up there.

The Harvest Moon series just has a lot. It's not super expensive until you get to the 64 and SNES.

It would roughly double since the games are usually only released in North America and Europe.
