Having read through Iron Cow again I realised that it didn't need much tweaking following the feedback Some I took on board so there are subtle changes to the artillery rules and targeting under firing but others such as set-up instructions I ignored as Iron Cow is not a balanced force competition game (it's a put what you have on the table, come up with a scenario and start playing game).
As you may have seen elsewhere we're adopting a two step approach to PDFing our rules, uploading the printer friendly version now which you can buy then adding a pretty colour document later (which customers who bough the vanilla edition can download for free). Consequently Iron Cow 2103AD is now available from Wargame Vault.
