A huge texture pack that will replace the NW units with early 18th century units.
Why not a 18th century mod?Because those mods never work, or come alive. With a huge texture pack you will still have the same amount of people playing. But still you can decide wether you want the NW units or units like this:
British Line infantrie
British Grenadiers
Swedish Line Infantrie
Prussian Grenadiers
You could even just keep the factions for a big part. Then change the skins and add some if needed, for example: the Russian grens didn't change much I beleave, so you can just keep those or edit them a little bit. Also: If there were mods in progress, but they quit their work. You might get some skins from them?
Just an idea, but I prefer having sexy stuff, but still the same experience with 100+ battles on EU1
