There are only two things I didn't like very much about the game, however:

1. First, I think the cars were way too big for the size of the road. I think that they should have been made smaller, something like 24x16 or if it's still a bit too big, 16x12. The car would look less detailled, but it would still look good I'm sure and you would be able to see more of the road ahead (and other cars).
2. Secondly, F-Zero is a fast racing game. F-Zero 68k is fast too, but maybe a bit too much. When playing it, the speed felt like I was playing F-Zero X or GX using an speed modifier action-replay code. Fortunately, controls were pretty great, so controlling the car was still somewhat easy, but judging by other F-Zero games, I feel this one could have been made so the cars moves at least twice slower. It would also make the tracks no longer seems incredibly short (I could finish some of them in 20 seconds)

Despite these two points, I think F-Zero 68k is a revolutionary game for TI calculators that deserves its feature and everyone who wants a good racing game should download it. It's pretty much like F-Zero for the SNES or GBA, just with twice faster speed and twice as big cars.
