Games that were difficult in your childhood

[Minusorange]

I was remembering back to my childhood of old games that were notoriously difficult at the time and I remembered Zarch which at the time I only got to play at primary school so no chance to properly learn it like you would a game you could play for hours at home but I always remember it being one of the most frustrating games I've ever played

What other vintage games did any of you struggle with or seem to remember as being hard ?
