If Shogun 2 was a slightly updated Shogun 1 using CLOTH MAP!!! Then just mod Shogun 1 for goodness sake

even if Shogun 2 was just a slightly updated Shogun 1 WITH MODERN GRAPHICS!!!, just mod Shogun 1 for goodness sake

I mean, then only people like ME would buy the game due to not having already bought Shogun 1 ... that and people that rely heavily on graphics
This is why games with extra moddability are so awesome because instead of relying on sequels for THE SAME GAME you can actually mod the old one (more easily)
If all games were highly mod-able then sequels would actually have to be GOOD ... and not a clone
consider Civ III -> Civ IV ... now that was a DAMN GOOD sequel. And that could at least potentially be attributed to the Editor that came with Civ III, where you could design your own units, buildings, maps, etc.
Due to the simplicity of the Civ III editor I was able to make my own little game of Dragons vs Undead
The Undead primarily focused on mass-production of units + buildings that would spawn certain units ... compared to the Dragons that used Super Units + an airforce
I might have eventually given the undead an airforce of Banshees and Wraiths if Civ IV hadn't come out when it did.
