Your fingers and wrists will need to be in top shape, too, if you plan on even completing a lap in the swimming event!
Play International Track & Field on the Playstation, the swimming event is even more difficult (pressing 2 buttons alternately as fast as you can but still try to get a rythm into it, then press a third button for the turn)
I still remember buying the game. It was in the Summer of 1999 and i bought Silent Hill (nevermind that i was only 14 and the game had and 18 rating, the guy in the store even told me to "only play it in the night") anyway, after Silent Hill i saw Summer Games and it was really cheap, so i bought it too. Sadly, there wasn't a manual so i never figured out the proper controls for the more advanced events.
Well i learned that i never liked that sort of games, so i played Summer Games only 2 or 3 times.
