A long while back, I dedicated my time to Tetris (on Gameboy). I surely spent less time on that than would have been necessary for chess, but it is amazing to see what progress is possible. I could play level 9[heart] without an end (in infinite play mode) or up to high 3 (6 rows of waste on bottom). When moving a brick to the left or right edge, the gameboy would make a long beep instead of individual blips. No idea how I could move my fingers that fast.

It is fun. For chess in contrast to Tetris, there is even a good chance for it to stay fun -- Tetris is a bit too simplistic for that, I think.
