I was influenced by a L. Sprague De Camp book of short stories as a kid. Picture of a dinosaur on the front and a time traveller that killed it and all the reprecussions of the event. Hard Science Fiction, although I didn’t know it was called that. Good stuff. Favorite was one which wasn’t really a story per se but was time travellers from different eras, all speaking English – one middle English, one modern English (which was 1930s i think) and the other 500 yrs in the future.
They had a LOT of trouble understanding each other. Loved it smile emoticon
