How to request a video game from a developer?

[Caleb]

What is the most efficient way to ask for a known video game franchise to be made on a certain system? For example, I really want some more games for the PS Vita and I want the companies to know that they would have a buyer if they made it. Obviously I am not going to support the company alone, but I feel like a little voice is better than none.

So facebook, email? or is there maybe a lesser known way to request games?

I already buy games new from the developers I really like, so what else?

I wouldn't know, but even if you made a request, the chances of any of them actually looking into is 0%.

The developers facebook page. If you just email them they will ignore it, but if you have 5000 likes, well they might listen.

Probably their Facebook page. Some developers do port existing games to other consoles so it's not unheard of for it to happen.
