You are playing computer games,aren't you?Yes,but this is the first time I ＿ computer games

正确答案是：have played.
固定句型：This/It is/was the + 序数词 + time + (that)从句,句意为“这是某人第几次做某事”.
其中要求that从句（that可以省略不用）必须采用完成时态.
如果是This/It is,从句用现在完成时；
如果是This/It was,从句则采用过去完成时.
句意可以进一步解释为“截至到现在/过去某一时刻为止,某人第几次做某事”,所以从句必须用完成时态.
