I think this would be worth implementing because it would allow players to download and install patches by simply starting their game and they would not need to know that a patch had been released.
This could allow this game's developers to release updates more frequently by releasing them in smaller patches. So if there was a gameplay spoiling bug, the developers could release a patch to fix this one bug as soon as a fix is available and "Corsix TH" players wouldn't have to wait for this bug fix to be included in a bigger patch.
Big patches could still be released on the "Corsix TH" website for players who have "dial up" internet connections.
A player's "Corsix TH" game could find and download the smaller auto update patches from a RSS feed.
