I used to think the same thing. A great man once said that there's a lot more to gain from keeping as many doors open as possible. But once you go through one all the others close. I feel this is the same with genres. Here are a few electronic tracks that are beautiful and expressive. It's all a matter of context and the medium. There is no best genre for games.
Do you think that Beethoven or Mozart wouldn't jump at the chance of using digital music to enhance their music or experiment with completely new sounds? You said that "Computers and electronic sounds CAN NOT FEEL.". The same is true about a cello or a violin or a piano. The instrument is useless by itself. But when a human plays it with a feeling in mind, then it becomes art and expressive.
