It's fun even for imaginary stakes, so long as they're limited. The reason you need stakes is not for the adrenaline, but because the stakes work kind of like 'life' in a video game. If you had infinite life the game would be stupid, because you could just rambo through everything. Same thing in poker. You could just go all-in every hand, because why not?

This is why some people like things like sit-n-go's or tournaments, where you pay a fixed sum once and then get a good amount of play in but where people will still take it very seriously.
