Fifa International Soccer on the Megadrive for me, then ISS on the SNES, ISS Deluxe and from there every single PES up until PES2009, where I switched to Fifa. I still bought Winning Eleven 2010 and PES 2011, but really didn't get on with them too well. Saying that, FIFA 11 was a let down for me, too, as the flaws in Career Mode really struck a nerve with me.
Yep more or less the same for me. ISS all the way through, 2008 was a I kind of like this FIFA but Pro Evo was still my main choice. 2009 was the year Pro Evo died for me after many many years of being my number 1
