Tetris is not my favourite game, but I have played it a lot. Why? I'd say it's because you get quickly to the satisfaction part. It is exiting when you get into hard situations and very rewarding when you manage to survive those.
Is there atmosphere in the game? For me it comes from the music and from the "Flow" feeling into which I get when playing the game and succeeding.
So what else happens when I play the game?
When I start it, I'm eager to get to the game. Why? Because I want to beat my highscore and my friends high score. I feel excitement when I check what the next piece is. I feel challenge and excitement when I try to figure out which position would be the best for the current piece.
I feel satisfaction when I can place the piece and especially when I can remove a row. This I enjoy and this gives me fun. I get worried when I'm closing the top of the screen. I feel disappointment whenever the game is over and again I feel eager to try again to beat my high score. This time I can do it!
