Like this? Breakout is a fairly simple game that requires only minimal animation. That makes it relatively easy to program. That doesn't mean it can't be done better. The breakout example I linked to it pretty choppy once you slow it down to a reasonable speed.
I wrote a DHTML version of Pong a while back that is far superior. Here's a link. The underlying architecture was very primitive when I wrote it, not having features like the Canvas tag available. And yet it is one of the better Pong variations on the net. (If you don't mind my saying so.) The reason for its superiority is simple: 95% of people who write a game don't understand what makes games interesting.
In the case of Pong, nearly all variations are too slow and the AI consists of stupidly following the ball. Well, that's not very fun. The ball should bounce fairly quickly and the AI should respond like a human. How do you make AI respond like a human, though? Simple: It should not act robotic and it should make mistakes.
The AI for Pong stops moving the paddle when the ball is traveling in the opposite direction. This helps remove the "robot" feel of the opponent. Next, the computer is limited to the same rate of movement as the player. This gives the player a chance to sneak one by the computer. (Since the ball is faster than the paddle.) Finally, the AI has a bit of jitter in its algorithm. Rather than moving with the ball, it computes where the ball is expected to be. A random amount of jitter is then added to the computation so that the computer has the possibility of "misjudging" where the ball will actually arrive. By adjusting the jitter, the game can be made to play on easy, normal, or hard. (Use the options menu to set the difficulty. Though for some reason, the menu doesn't work on Chrome. So just be aware of that issue.)
Another game that is rarely done right is Tetris. Take the Jetris game in the "GameJS" link. It's a nice tech demo, but it's a sub-par game. And not because the game is of the "classic" Tetris variety. (My own Tetris game was of the same variety.) It at least gets the coloring right in that each piece is a specific color. (Though adhering to the Tetris standards for coloring would have been an improvement.) That's a good first step. The bigger issue is that the piece selection does not have a very good distribution of pieces. I regularly get three or four of the same piece in a row. That should never happen in a good Tetris game. Programmers need to take steps to ensure that the player will never get more than two of the same piece in a row. The Tetris "Bag" algorithm is a good solution to this that makes the game more fun. Another good trick is to ensure that pieces always arrive in the default rotation.
Anyway, the point of my rant is that the technology is rarely the problem. A good game programmer can make a fun game out of nearly any technology. An inexperienced game programmer with no understanding of what is "fun" can make any technology look like the problem.
