You should remove the RUSSLAND and WEISSRUSSLAND labels, they do nothing for gameplay.
The Valdai Hills label should also be removed - there's no need to identify that one particular area and it's the only terrain feature so labelled.
The naval-related texts regarding the Baltic mine zone and the Black Sea should probably go as well. The naval game is so abstracted that players don't need to reminded of fleet strengths.
As I mentioned before, those shipping lanes serve no purpose that a port icon wouldn't show - it's not like the player is limited to moving along them and they clutter up the map.
Please understand that I offer the above as feedback to my particular tastes and I applaud your effort in general (I'm using the map in my games). But if I learned anything in my career in software QA is to beware of scope creep. You started out doing the town names and now you're listing the number of destroyers in the Black Sea. Keep it simple and keep it relevant. People want to know town names, port locations are useful, and it's nice to know where the factories are. The rest of the stuff just clutters up the map. I know you're having fun and you're thinking what else can I do with this and what other information can I show or what flavor I can add, but at some point it's time to finalize the deliverables and close out the project :)
No problem at all. I kind of went around in circles with each of those items. I'll see what others have to say and go with what I feel is the majority view and upload a patch soon enough. If it really bothers you, PM me your email address and I'll send you a clean version of those map squares.
The Valdai, Russland and and Weissrussland labels crept in because I based this mod off the Frontline Mod by GoranW and his maps showed that text. You will notice that I only put the names on one map each in the end, while Goran has put them on several.
I find things like the Valdai useful because I play team games and it struck me that some newer players won't necessarily know what you mean when you say "head for the Validai"... But I agree with the Russland text.
The Black Sea stuff doesn't clutter the map, IMO, as it's just blue water. I though that the game failed to explain the naval interdiction concept clearly to a new player, so by making the point that there's a naval struggle going on out there, I hoped to illuminate that issue.
On the question of the sea lanes, that's going to be a matter of taste, as you say. So many new players have posted questions that relate to sea supply and sea evacuation, that it seemed important to really highlight the matter. It's really useful up around Leningrad, IMO, as a reminder of how far you need to go to truly surround the city. However, when time allows I will create a 'Sea lanes' and 'No Sea lanes' option. Hopefully you can live with it until then? If it's really bugging you, PM me on that as well and I'll sort something out for you.
