Fair enough. Here's a concrete suggestion for you to consider:
1) I beleive the New York only Ironclad production for the Union will in the end, be viewed as too restrictive. New York is one of the best states to build factories early in the game because of all the infantry rebuilds that will need to be done there later in the game, plus the generally high population that is available. From a practical point of view, I think that the Union will not be able to get the 12 ironclads out there by mid-63 under the proposed revision. SUGGESTION --> Add New Jerswy back into the mix. The extra 3 production points should be enough to relieve the congestion.
ALso remember what Ironclads are there to do -- shoot at HA in forts. WIth VA, GA, AL, and TX still capable of building HA, I do not believe you have restricted HA prodcuction anywhere near what you are proposing for Federal Ironclads. Shooting at HA in level 2 forts is HARD, and takes a lot of ships.
2) Not to disparage the great city of Memphis, that is where I would take ironclad production away for the CSA. ALlowing it in NO should be fun, because of the map changes that are in v.03.
As an aside, I do not think that it is all that likely that the CS would lose it ironclads in drydock iff they commit to the project on turn 1. Start building all 4 on turn 1 or do not bother. Add in an Arkansas gunboat, and you have a very nice fleet on the Missisippi river, with nary a Union Ironclad to be seen.
Me like eating Federal Gunboats -- taste good and crunchy too!
Gshock -- as to whether this is something you SHOULD do -- that would have to be decided on the battlefield, now wouldn't it ?!?
