1) You could say:

"This is a game I have played before" or
"I have played this game before" or
"I have always played this game".

You can't say "This is the game I have ever played". The correct sentence there would be "This is the game I always played" or "This is the game I have always played". The distinction is subtle, but "I have always" implies that I still play the game, while "I always played" implies that at one period I played it, as "when I was a child this was the game I always played", but I no longer play it.

2) You have a choice:

"We can't ask anything more from the players" or "We can ask nothing more from the players". You only need one negative, and either one will be fine. Also - it is more customary to use "of" rather than "from" here, though both are correct.

3) b) is correct.

Thanks for your reply.

For 1), if i want to express the meaning that i have never played this game before. can i express it in this way:

I have ever played this game.

It seems to me that "ever" and "never" could sometime be interchangeable, is it correct?

- But for centuries this would have been perfectly acceptable English; "ever" used to be a synonym for "always" (and logically, the antonym of "never"). It's possible that the original poster came across this phrase in a pre-20th-century text.
