What are you talking about there's plenty of Solitaire Games in the store, and you don't have to pin them onto the Quick Launch bar, just grab the tile and put it wherever you want, or right click and do what you want with it.
Use the search in the charms bar when you're in the Store, you'll find most of what you want. Just did a quick check it brings up a 124 apps for Solitaire and the Microsoft Solitaire Collection is there.
Oops, guess I didn't look far enough, but what I saw wasn't what I wanted. I'm still learning Windows 8, and still not sure I'll "keep" it.
Search in the Charms bar, eh? Really? I don't find the charms bar very charming.
However, I'll go back and look.
Oh, and I
want everything I use pinned to Quick Launch; it's more efficient for me. Yeah, playing a game is efficient . . .
