Re: Do I have to buy the other C&C games to play 4 or not?

Hi,

You can buy C&C4 as a standalone if you wish, with no needed to have any previous games in the series. Here's an Origin link if you're having trouble finding a physical copy.

That said, you mention that you love RTS games, so you might want to think about the C&C Ultimate Collection. It's got all the C&C RTS games so far and even a FPS to mix things up. Anyway, I just thought I'd mention it.

I hope this helps.
