>>Q- Just read that there will be only 13 units on the map is this single units or groups of units like the total war series, and I know you can build more but what’s the unit cap if there is one?<<
The important thing to realise here is that there are around 60 upgrades that can be applied to the units and that the opposition doesn't necessarily know what you are upgrading (but likewise, you don't know what the opposition is doing either). Some of these upgrades might be temporary, some of them might be permanent. It makes combat very dynamic.
>>Q- Can you upgrade your ship base? And can your base ship participate in battles? <<
No
>>Q- Are all of the land units robots or will we see soldiers on the battlefield<<
We don't really think of them as robots - there's humans in there.
>>Q- is the over world map static or randomly generated, and if not how many provinces does it have? <<
There are different campaign maps that have been hand-made. It think it's likely that eventually we'll come up with a random generator.
As far as unit caps are concerned - there is a natural cap due to the maximum population of a country. When we'll be done with our press tour we'll release a walkthrough video which should explain that mechanic in detail.
