If you want an easy game, be able to score from the half way line and like all the correct names for the teams.. then Fifa is for you. HOWEVER, If you want the best challenge possible and more realism, then the Pro Evo series is the one.
My personal favorite is Pro Evo 6.
The best football sim ever.
I'm afraid that you'll find that FIFA is no longer the strike and score that it has often been in the past. Never having played Pro-Evo, I couldn't tell you which is best. But FIFA is now a very challenging game in my opinion.
FIFA is still **** easy, bomb down the wind wip in a cross and head home. Personally I still like it, I did like pro evo's more indepth game control system but to be honest if you want more of a challenge just play on a harder setting.
I have had both and sold both but if I were to buy one again it would be FIFA.
Absolutely no question...pro evo 6 is head ,shoulders,thorax,abdomen,groin,thighs,legs,ankles, feet, toes ahead of fifa........go for pro evo...you will not regret it i promise you!
