I'm tired of being bashed for being a retro-gamer, i debate and shut must of them up myself but once in a while you get a total ****

Here is a line one person said recently to me

"so much new technolagy"
"y go back to old stuff LOL"

Or "90% of old games are sh**" 

And some people think a game has to be a badass fps to be fun as well.

What are some debating points i can use that will shut these idiots up?

I'm 16 years old by the way.

Thanks  :)
