不错，感谢了

惊天动地私服应该收费吗

[b][url=http://www.251700.com]惊天动地私服[/url][/b]本就不是该把重点放在玩家身上获取利润的产业.惊天动地私服，说到底和电视一样，是个娱乐媒体而已.大家看过看网站还要付费的吗?（非法的除外）

网络游戏的生存，说到最根本还是在于人气，代理商考虑的首要元素就是人气!你服务优秀，游戏开发的成功，自然人气就涨了。有了人气，可以做很多事情，比如有名的NEED FOR SPEED系列，他们的重要收入来自广告，他们把各商业公司的商标溶入游戏的场景。其广告收入就非常可观.而网络游戏如果人气很旺，那此官网的点击率将会很高，那也是价值所在.

打个比方来说吧，你的官网点击率高了，副业就来了，可以关联相关客户的网站利用游戏官网的点击率来提高客户网站的点击率，使得客户网站在google的排名有一定的地位。我国的部分网游实在太急功近利。伤害的是玩家。
