What all is expected of a game?

[hey]

I know I've been asking a lot of questions, but hopefully this will be it for awhile. Right now I'm working on what will hopefully be my first complete game, and I'm wondering what future viewers of it would expect in terms of performance. I've been looking through the internet recently, and I keep hearing about things like blitting and double buffering. Both of which are pretty foreign to me (I understand the concepts but not how to apply them). I'm interested in these because supposedly they can help remove the flickering effect I've noticed while testing the game.

So, my question is, would the average viewer care enough about the flickering for it to be worth me trying to obtain a better grasp of blitting and double buffering? It seems that if I tried to adopt those ideas, that I would have to completely redo everything else as well. Also, are there any books that deal with this sort of stuff? The only ones I have right now seem to consist of moving something from point A to point B in different manners, which leaves me little knowledge of this sort of thing.

Thanks, and sorry for the long post.
