SEGAs Virtua Tennis 3, which ships to PS3 and Xbox 360 next week, is
one of those games thats hard to drastically improve because its
already so good. They really nailed the controls, the feel, and the
animations in the first game back in the arcades and on Drreamcast.
Still, SEGAs development team has pushed for more mini-games, a
greater single-player campaign, and now, for the first time, online
play. One of the big differences between the Xbox 360 and the PS3
versions is that the Xbox 360 version supports online. That is, its
fully Xbox Live compatible with various modes of play, leaderboards,
Achievements and GamerScore points. The PS3 isnt online. Simple as
that.

Overall, Virtua Tennis 3s Xbox Live support is solid stuff. The game
looks good online, it plays well, and the human-on-human competition
is absolutely fantastic (when there is no lag), especially when you
have smack-talking friends with whom to play.

(when there is no lag)

That's the point

注：
我没有在评价国内网速问题
我只是对网球游戏对于lag的超敏感性表示理解

没有延时是关键啊

嗯，有网战大不同

国内电信和网通连GOW有将近1秒的延时,打苦役很受罪

同一个游戏.差别咋这么大呢

因为微软的live平台是现成的，可收费的
而且由不同小组开发。
等游戏出来了就可以有比较帖了
