I’ve given up waiting for the ‘Base Set 2’ as suspect will be ‘vapourware’ - this thread highlights why - there is no point HBG printing off a unit in 10 different colours, if certain sculpts are rarely if ever going to be bought by a certain nationality (and hence bought from HBG), and that will apply for a lot of the advanced tech stuff.
Therefore bought the 3d printed versions of the Base Set 2 items I needed, so Maltas for heavy carriers etc.
My approach has been to paint up at least 1 of each advanced unit, for each major power, and then more where I think countries need them/are likely to use them in game.
So Russa can build 1 attack transport and heavy carrier before I’m stuffed, but America has 3 sculpts of each of these units (for example)
