I can see the confusion with the text "(after playing this)" As I think you all already know, this was meant to help clear up any confusion about Actions being used when an Action is first played and not upon its resolution, but it does a poor job getting that point across. You all seem to think it's not needed, so that's good enough with me for removing it! Thanks for the heads up.
I should however argue that I think the phrasing is fine. I only bring this up, because at some point I might make a card that cares if you have Actions left and has a check for that at some point in the cards instructions. For instance: +$2, If you have Actions (after playing this),
some effect. Here I think the "(after playing this)" is much more helpful in relaying the check happens mid-way into playing the card (i.e. after using an Action to play the card).
I'm basing this off the notion that playing an Action has three phases: (1) Play the Action, (2) Following the Actions instructions, and (3) Resolve the Action. Of course the rules don't quite phrase it this way, so I admit I could be wrong here. Would love to hear more from you all! Does my argument make sense? No sense at all!?
At any rate, here is the changed version (v0.2) of Sunken City. Thanks for enduring my rant.
