If you haven't seen the announcement thread yet,
please take a quick look here.
Also keep in mind
the development diary.
But with that out of the way...
Welcome to the Blue Water official suggestions thread!
To call the development team here small is an understatement, and many of the features have yet to be fully committed to.
As of the moment, we have for our game's core:
1. Realistic weapons and ranges
2. An adjustable "world scale" slider that modifies the range of all weapons and sensors
3. Time Compression
4. Skirmish and multiplayer modes
Etc.
It's impossible to list every little feature of a game, and maybe it's hard to come up with specific feature suggestions on something you've never played, but people have had a lot of years to come up with "what I'do differently about [similar game here]", and I'd appreciate feedback.
The project is for you, after all. So what have you always wanted to see in a realistic naval sim in the genre of Jane's Fleet Command or Battlestations: Midway? (leaning more towards realism)
