Thank you for starting this thread Meepledrone. I'm already looking forward to the many spirited discussion it will generate, lol. So lets get this party started.
Think the first area that needs serious work is the C2 version of Order of Play in regards to expansion 10 Under the Big Top when placing and scoring acrobats. As it is currently written, it is impossible to properly play and score acrobats.
----------
From the rules:
http://wikicarpedia.com/index.php/Under_the_Big_Top#Acrobat_tilesAfter a pyramid has been scored, players can start a new pyramid on the same tile by placing a meeple as an acrobat on it.
----------
From Order of Play (select only Exp. 10 - Under The Big Top):
Step 2B-1: Move the Wood (Phase 1)
You may do one and only one of the following:
Deploy a meeple.
Normal meeple
Ringmaster
Perform an acrobat action if the tile was placed adjacent to an acrobat tile:
Add a normal meeple to an uncompleted acrobat pyramid.
Score a completed acrobat pyramid finished in a previous turn.
----------
The current rules and the Order of Play aren't in sync. To get them in sync, we need to move the scoring of the acrobats outside of section Step 2B-1. Lets see if we can clean this up.
Here are the conditions:
1) Be able to score a completed acrobat pyramid, after the placement of a new tile adjacent to the acrobat tile.
2) Be able to place an acrobat on the same acrobat tile, that was just scored, after the pyramid has been removed (due to scoring).
The only way, at present, I can see to fix this condition is to add a new check and resolution phase for scoring of the pyramid on an acrobat tile. It has to be done between Step 1C: Place the Tile and Step 2. Placing a meeple.
As far as I can tell this change should not impact any other expansion interaction once completed.
Now for the fun part. Wording. Thankfully this section already exists
Step 1C: Place the Tile
Place the tile.
Note: any feature that is finished is considered complete at this time.
That note is exactly the condition we have. The check and resolution of the pyramid, on an acrobat tile, happens the moment the new tile is placed next to it.
So lets add a step G to fix this issue.
g. Check the tiles adjacent to the one just placed. For each acrobat tile found, check for the completion of a pyramid (three meeples) on that tile. If found, the owner of each meeple is awarded 5 points. Return the meeples to their owners.
Remove from Step 2B-1: Move the Wood (Phase 1) subsection b "Score a completed acrobat pyramid finished in a previous turn." and that should fix everything quite nicely.
Ok, let the fun begin. Does my solution truly fix this issue?
