By the looks of it, it doesn't seem really different than the old food/hammer/money system of the average 4x game, unless I'm missing something. Same for the tile system. Even pop doesn't look very in-depth... I had hoped for something more original and refined from Paradox.
The way they described it, "materials" are not the directly equivalent to "hammers", neither is "energy" to "money", so there might be a bit of variation there. I don't think trade deals will be done solely through energy, for example. Materials will probably be exchangeable as well. It is not extremely revolutionary, but it is not a straight up port of the Civilization formula.
