(Sorry if wrong forum, best guess)
Have you ever been approached about your (did not succeed the way you hoped) game - it never got traction or found a market - and had someone say 'I like your concept, lets work together to repurpose this and re-release it as something new'?
If so how did you respond? Or how do you believe you would respond?
Would it help if the person was well known in a niche market and carried a pre built publicity machine with him (not famous in the general sense, but for example very well known in the area of ...oh, "sticky note history" - for fans, this person is a star, but the rest of world would never heard of them)?
