I think Steam should start to sell Android games.

For why?

They already do. It's called Greenlight

I know that some of the games I own have ports on android, I even got some of them from humble android bundles. I think it would be nice to have the existing android versions of games I own for the PC, and by extension, I'd find it nice to have steam sell android games (to an extent). Though for now I'd mainly just like to see the steam app getting worked on a bit.

The company's name is still Valve.

And i don't really care as i don't play mobile games.

I approve, but iOS too please. They can sell Mac games, why not sell iOS too...

Half Life 3 will be a mobile game.

I don't think it would be that good, because the company will probably be really lazy and just port the game to PC with crappy graphics, and unresponsive controls. It's definitely worth a try, but ass PE99 said "The company's name is still Valve". I don't see why they would really sell Androids games.

Hell no.
