It's a matter of trademarks, not copyright. Trademarks don't run out, though they must be continually used. I'm pretty sure Pacman would be considered to be in use, as it's a very well-known brand.
A visit to Namco will show you they are still actively promoting it by porting it to new platforms, as well as continuing to develop it as a franchise.
I think no??? since this is game we are seeing since childhood so , you cannot use its name. And its the most popular game in world, just like mario, tetris etc. So better dont use names that exists from decades instead use some other similiar type names, if you want.

这是商标的问题，而不是版权的问题。商标不会耗尽，但必须不断使用。我很确定 Pacman 会被认为正在使用，因为它是一个非常知名的品牌。
所以你必须使用不同的名称。

So you'll have to use a different name.
访问 Namco 会发现他们仍在积极推广它，将其移植到新平台，并继续将其开发为特许经营权。
所以答案是：不。不。同样，不。

So the answer is: No. No. Also, no.
我觉得没有？？？因为这是我们从小就玩的游戏，所以你不能使用它的名字。它是世界上最受欢迎的游戏，就像马里奥、俄罗斯方块等。因此，如果您愿意，最好不要使用几十年来存在的名称，而是使用其他类似的类型名称。
