It's hard to know for sure, but I think this is the one I spent the most time with. Played a lot of the in the years before and years after, before only going for Pro Evolution Soccers and ignoring FIFAs for years. Game still looks amazing to me for 2001, having power bars for almost all non-panic moves is bonkers and it's so hard to do anything correctly, but it creates a lovely mess on the pitch. Still can't pull off my trademark goals straight from the kick-off I mastered back in the day, doing that was insane.

Visually and audibly impressive, messy but refreshing mechanics, decent database with some questionable choices in both names and attributes on top of iconic soundtrack (can't beat 19/2000 Soulchild Remix), it's hard to have too much against this.
