For whatever reason I find the opposite is true. Kids usually seem to be more open to change, and whatever goes than the older players.
When I was a kid I thought Super Mario Bros 2 was awesome, even though it had little connection to the first, and played different. I still hold that SMB2 is an awesome game, and a worthy Mario addition. But if I was me today, and I saw such a thing released, would I feel the same? I'm not sure I would be quite as welcoming and open about it.
Some of it was perhaps, you played what you got since you didn't have so many games purchased back then. At least, I didn't, nor did my friends. These days however, I find myself sticking with a certain genre set of games primarily, and very rarely going outside those bounds with the exception for when I am studying them.
