replyYou can put the mangled headline into actual English by shortening it:
Why Microsoft Entertainment Pack had a sticker announcing that it had Tetris
How about
reply> Why did Microsoft Entertainment Pack announce that it had Tetris
The sticker seems like an important aspect.
replyWhich the article can state, but the headline needs to fit.
replyWhy it was announced specifically on a sticker (rather than on the box like the other games) is the core of the question - the headline no longer really works without it. I'd go with one of:
reply> Why did Microsoft Entertainment Pack have a sticker announcing it had Tetris?
> Why did Microsoft Entertainment Pack announce that it had Tetris on a sticker?
> Why the Microsoft Entertainment Pack had a sticker announcing it had Tetris
But doesn't really matter that much.
