I feel like at this stage, I could ask any regular reader of this blog for a short list of things that I really like to see in games and anyone keeping track would have an easy time figuring it out. Perhaps you might start with a narrative, or some king of story-telling device that plays a central role. You might then add in some kind of aesthetic importance, where the graphics can be considered art, and they play an important role in telling the aforementioned story. Finally, even though it's not as obvious as the others, you might think to shape the game mechanically as a traditional point-and-click adventure. If you did all that, you'd undoubtedly be pretty close to a game that really can't fail to impress me.
