How does the Improved Battle System look like exactly? Are you talking about the FBS or the SBS?
What does the Menu look like?
Same goes with the HUD.
Without a mock up, we don't know how we can start to help you. If you can provide images of how they'd look, I'd be happy to see if it is under my belt to help, etc.
Right now the most important part would be the battle system we want it to stay in a side view position. when you are on an active player to choose what their next action will be you would see an opaque version on that character on screen. Like in the bottom picture but it would be on the side of the players instead of the enemy side.I would also like the options for the player to be in a corner of the screen as wheel as you can see in the bottom picture. I would like the player stats to be on screen as seen in the bottom picture. A victory aftermath page such as the middle picture would also be needed as to make sure the player understands what they have gained in a easy to understand visual format. Lastly I would like the enemies health to be displayed like the bottom picture. There would be small changes to the way messages are displayed as well however those would minimal change.
In according with the Menu of the game I would like the Menu to look like a book that is being read from. I would like the words to fade in and out on the page depending on what you chose, certain menu's like the Equipment menu and Status would look something like this in book format as well.
Were looking for the HUD to be as minimal as possible but still give players what they need. We would like the HUD to include a small mini-map that has coding to include symbols based on what we put in the game engine itself (with a script call event), A character picture of the current character with their health and magic bar much like what is shown above in the status window. and if the character has a sort of effect on.
The weather system would simply be a way to change the weather based on what time of day and year it is so it would change the way the screen looks and what type of shading effect is on as well. This would also affect the battle system a little in a small way. i.e. if it is raining fire attacks are weaker, if it's snowing their even worse.
If you have anymore question please feel free to ask and if you feel as if all of them together is to much we would appreciate any of them that you could do.
