Unfortunately, tournaments aren't seeded. You're simply given a draw when you start out, and play through until victory or elimination. It's not a big deal, but the extra drama of starting out as an unheralded youngster getting the chance to upset the top seeds would have been a nice touch. Gameplay within tournaments and single matches can be tweaked to just about anything you desire. Actua Tennis is an attractive title.
Acceleration is handled very well.
Players run, swing, and leap in a very realistic fashion. The stiff, Frankenstein-like player movement seen in other sports titles that take advantage of 3D hardware is nowhere to be seen. Stadiums and court surfaces are also similar to their real-world counterparts. The grass texture is quite lifelike, complete with the brown patches that always show up at Wimbledon after a few days of heavy play. Clay looks dark and slow.
