This was one of the first computer games I played.
I had this, Chessmaster 2000 (good!), Rolling Thunder (bad) and Ferrari Formula One (terrible), for my Amiga 500 lol.
It's also the only computer game that had me literally crying (because I lost to France 1-2) - I was 9 years old
In the world cup you could choose to play a team at any moment, so me and a friend did this when the final came up (of course we couldn't choose which teams did make it there), anyway this frustrated my brother out of his mind.
I'm using the keyboard and as for the controls I first used the arrow keys, but is hard to run diagonally, so I switched to the numpad, and use the spacebar for shots, tackles, and passes. Are there more controls?
Gotta love that banana power option!
