To impress someone, you have to strike a chord with them. You need to give them something that resonates with them. Something they care a lot about. As much as I love FF games, they're not my entire life. In fact, if video games would suddenly stop being made tommorow, I probably wouldn't notice. I'm paying a lot more attention to my DJing career right now, but even if someone gave me a great compliment regarding that, it would feel superficial to me. I think that talking about someone's personality (things that they do, views they have, their general mood, etc.) is a much better way to move someone romantically speaking. It worked on me, and it's worked for me. I also try to think of different ways to say things. For example, instead of "you have beautiful eyes" I might say "I am enamored by the infinite depth of your radiant eyes." It's not Shakespeare, it's not even Bacon, but for me at least, it's honest.
