How good is Naval War with 1:6000 Scale

Have buyed from MagisterMilitum many Z-Plan Ships. Pocket Battleships and Flugdeckkreuzer.
1. Is there a chance to play with them in Naval War?
2. How Easy or Difficult is the Game?
3. Can i free build a fleet?
4. Is there a chance to play other Era and Crossplay? HMS Dreadnaught vs KMS Bismarck?
5. I want to alter the Ranges and Speed, to play it with smaller space?

Cheers Michael

Thats a lot of questions.
1. Not yet until I add the datacards for the ships. Currently I only have the H39 added for the germans.
2. The game is not too difficult for a Naval game. Comparable to Victory at Sea and Naval Thunder. If your not familiar with miniature wargames it can be a bit harder to learn.
3. You can build any fleet you like, the points costs are on the cards. If you want to play somewhat balanced or competitive I'd advise to look into the Order of Battles.
4. Not currently, I've only added ships from WW2 currently
5. If you play 1:6000 I'd indeed advise to change the ranges and speed, maybe cut all of them in half to get a more realistic game, your only problem then will be the torpedo template, but you might manage to just print it out at 50% size?
