A true classic. Larry Niven's work still holds up well. The only aspect that might date it is the few references to "tapes" with regard to a visual storage medium. I was surprised that so many questions went unanswered such as who built the thing and why considering the book was not intended to be a series. Still, that does not distract from the story which is very solid. The one part about Teela Brown wanting to remain on the Ringworld with a guy she just met and doesn't even know much of his language because she 'loves him' seemed a little far. One could argue this is because of her 'luck'. Still, how would she know? Then again, luck I suppose. Of course so many plots have been centered on 'love at first sight'. It is nothing new.

Regardless it is a great read for anyone that enjoys a solid science fiction story.
