Indeed, with the faction and model limits raised, we have a lot of new possibilities for modding. However, we can't really make a good use of the increased space in those areas if we can't get things like a few more culture groups (TA said 10, that would be sufficient I think), or even--if it all possible--some more unit and region slots. Now, even those last two, we can get by without those if we have to!

But we simply won't be able to do the increased faction possibilities justice without some more culture slots.
