I am looking for an old sci-fi book that takes place in the future. People are living to be hundreds of years old and a man gets the Nobel prize for inventing a new video game to prevent boredom. He meets a girl that works at a government job and they discover a secret. As they are trying to get away she gets captured and they hook her up to a machine that puts her into some kind of cryosleep. And that's all I can remember about it. I think it has game in the title but I can't remember. And I don't remember who it is by.
I think it was written in the sixties or seventies. I don't think that it is very far in the future now, maybe like 100 years or so. I do believe there were robots and flying cars, teleporters, I don't know. The video game technology i think is still consoles and some virtual reality. On the cover is a guy and a girl running in fear and they are in front of regular sized building shaped like pyramids. Right now that's all I can remember.
