I have 2 picks:
PES (yeah it was big in Latin America and Asia but never truly beat FIFA popularity worldwide except in the early 2000s), if I had to pick a specific version, is either PES 2010 or 2013, 2016 was also great.
FIFA street 1: Almost 2 decades later and still think it’s the best FIFA game ever, not even the street sequels were able to surpass it. FIFA 11 and 13 were good too but those aren’t underrated in any way.
Blitz the league 2.
Was a departure from og blitz but was my childhood. Violent football with emphasis on injury and dirty play
Fun if a bit cringy story looking back. Having to pop your players leg into place with mini games and getting a sniper elite level cam when you injured someone.
