Re: Fifa 11
I don't think the system is good enough (stating the obvious), I understand the way they are going about it as Roma explains, however the major flaw in that system is that the increase in cpu difficulty feels as though it's a fake increase in "stats".
Just because the higher level is still an accurate representation within their stat range only highlights that the rest of the skill level is manipulated to be less.
Essentially the end of match boost should be linked to tactics & mentality. So if a team has 50% aggression that should dynamically change to 80% if behind, same maybe for pressure and a few of the other settings. An extra level could be tactics (formations, players, etc). As long as the new use of stats and the fatigue is properly done the mentality/tactics should be enough.
If anything in real life teams don't improve in the last 10 min. with more concentration or faster reactions, they change mentality more then anything. Champions are created because of their mental ability, not physical! Look at how many last minute goals teams like Manu score, it isn't that Rooney has decided he needs to wake up and be more precise, it's the mentality to be able to have give more pressure and take more risks whilst keeping their skill level the same. That is what differs between players and teams.
And the same can be said for gamers, it's their ability to keep their skill and composure in high pressure matches/situations that makes them better then the others.
And thinking of an improvement for FIFA12, how about dynamic custom tactics. It's being introduced is PES this year and is a basic element of football.
