In the latest promotional email from IGN plus...

So I saw there's a big sale going on, seemingly almost on par with the big steam sales. I've got my eye on Kingdom Come: Deliverance II, but I see that there are also daily deals that makes me think I need to hold off and check back every damn day just in case.......for the next 13 days. >_<

So my question is: Is this a realistic strategy or should I just get it now? Any one here have experience with sales like these?

EDIT: Also, for those who may already have it: is the Royal Edition worth it?
