Which first party and third party have you played the most IP's from?

SE they have so much stuff. And even the bad FF spinoffs I have to try, even if I know they're going to be bad :P. And since Eidos was my favorite company for a long time all their games count too.

Nintendo is the other company, where a lot of that criteria fits as well.

I'm not going to count, so one of those.

I'm also not sure listing blizzard was necessary since they make very very few games, I think Actvision Blizzard should be 1? Square-Enix-Eidos is considered one.

Look for a website with a stable of the franchises of the company you've played the games on owns.
