Wintervice

I've got Lion on my iMac and any time I open the store it still crashes. I even tried to reinstall it via the instructions at the start of this post. (though I realized later it was for if you had trouble patching.)

My husband, who has a MacBook Pro and has Snow Leopard can access the store without crashing. (He mainly plays on a PC though)

There was one I liked before that the author recently updated (so I had to run it again just in case).

The Heart of a Gemstone (ID 504716)

A decent number of custom enemies, and a tragic love story you can make untragic (is that even a word?).
