Can I make game (not mod) in Source SDK?

Can I make commercial free game with Source SDK 2013 Singleplayer?

Can you? Yes you can
Should you? Most likely not

The engine is not really supported anymore as much as I remember, meaning its better to use a different engine
I think I can dig out the place Valve talks about it, and the place someone ask about using it, and they recommended them not to do so

So here is some info:

ㅤㅤQ. Is there a licensing fee for using the Source Engine?
ㅤㅤA. There is no fee for using the Source Engine for your free mod, but there may be licensing fees for included tools if you charge money for your game.

and this may not be able to be seen by you, but you can see here Valve saying they basically don't recommend to use it except for mods at this time:

That's not problem. I have complete demo of my game, but I did not know if I had to pay for Source SDK license when I made this game for free

Sorry for my English because I'm from Poland
