AVault heeft een review van Fifa99 gepost. Zoals gewoonlijk zitten er weer een hele zooi verbeteringen in, waaronder de AI:
The other area of real improvement in FIFA 99 is in the AI, both for the opponents and your teammates. I am glad to see that your opponents are a little smarter and play defense more realistically by playing off their mark when I'm far from the goal, but tighter and tighter as I approach the 18-yard box. However, even better is the fact that my teammates actually play like teammates. A good run down the wing or pass to an overlapping player (using the overlap command) is more useful because I can actually count on someone being in the box for the cross. Plus, for crosses on the ground there's a new slide tackle that lets you stretch for balls you might not usually get to, and when you score this way it looks very, very cool.
