Sorry, but I wanted to add in a few comments of my own here.
With both the No Hand Bonus and Zombie Quartet, you can still „skirt“ the draw before play and win, if you have the right cards (and it’s always if you have the right cards). Why? Because you can use your weapons at any time during your turn to kill off zombies in front of you. Of course, at this point, that isn’t considered a play, just the ability to observe a New Rule (I believe they both say MAY on them, not MUST) so one might argue that you aren’t actually skirting draw before play, but you are still performing an action. However, if you are playing regular Fluxx, there isn’t a whole lot you can do without having any cards in your hand, so drawing first in that case is pretty much a must (and only contains a negative connotation if you have the Radioactive Potato). As well, regular Fluxx ignores the Zombie argument.
More chaos to this one. Let us assume (I know, I know) that there is a Play 5 in effect, along with Final Card Random. Now, I play 3 cards, for my fourth card, I play a Play 3. Playing the Play 3 becomes my final card, however, since it was not in effect until it was played, it was not my final card until it is played. My final card did not end up being random, but no one could prevent me from going around the rule this way, correct?
Granted, this seems
picky, but I understand what you're saying. I think this part is quite
obvious - but then again, you thought the "you should draw first" was
obvious. And I do know plenty of Rules Lawyers who would go to town on
this part of the rule.
As far as I can tell, you can play cards as they come out instead of waiting until you draw them all. Why? Because you may (or you may not) play a card which raises or lowers the amount of cards which you draw. In either case, you observe the new limit, to the best of your abilities, not continue to observe the old limit. Although I can see this getting confusing when there are multiple bonuses. For example, it’s draw 4, parent bonus, and you have the computer. You draw four, and play a draw 2 before continuing. Do you draw two more cards (4 from the draw limit plus 2 bonus cards) or did you draw all of the cards your allowed (2 plus your 2 bonus cards)? However, from experience, most players tend to draw all of the cards they are allowed at the same time to give themselves the most options. But, Zombie Fluxx may change all of that. We’ll have to see.
As has been noted, making sure everyone knows what is allowed at the begining of the game, no mater how you play, is what is most important. Otherwise you end up with people going „I didn’t know you could do that!“
