Battles: I'm partial to Chrono Trigger style fights, but classic Dragon Quest style is just as good. You might want to think about damage formulas, too.
DQ-style? Alright. Seems it's the best choice anyway. As for formulas, I'll be doing that too. Elemental strenghts and weakness, weapon versus armor, etc.
I'm acceptable with the on screen and the random, but on controlled areas. (Can the game have different difficulty levels?)
Yes, there can be difficulty levels.
876: 876 is dependent on how much more effort you want to put in. How complex is the script? Are you going to be gutsy and change the script based on the characters you have? If so... this will exponentially increase the amount of script to make. I'd say gauge your decision based on how you want dialog to pan out.
I plan to base the script on the number of characters I'll have. The script is no object to me, to be honest. *shot*
They can join as our allies. (I just thought of something, what if they got kidnapped by Jupiter due to they obtained something valuable, save them and we can use the item.)

Woah....I'm loving me some weapon designs. XD
If they'll be NPC? Sure, why not. Though I must know at this point whether to add them or not. (I can still fit in the Valuable-item-from-876 plot either way)
961: As enemies... there'll be no further complexities I don't think. Putting them in is just as much effort as leaving them out.
I see. Now, as to how they appear.....
Yes, please! (They can become mini-bosses or bosses, or they can be like childhood rivals in Pokemon everytime you meet them, beat em'! 
)
Maybe the combination of the two? XD
Producer: Will there be conceptual gameplay changes? How about script changes? Again, you can decide on one for now, then add in stuff if you feel you want to change it. Programmatically (if you indeed think there will be script changes), you can stub in a conditional and just set said variable when the game starts. When you feel the need for a select option, you can make it then (and remove aforementioned hardcode). If you find it unfeasible, just leave it.
Sure, why not? (Gotta see the difference between male and female)
Script changes are guaranteed (more yuri *shot*). As for gameplay changes, I was thinking of making the male more physically focused while the female more mentally focused (like in common cliche systems). There can be more. I've only thought as far as that for now.[/doing script]
Music: This decision can be saved for later, if you can't decide. It's really a matter of overwriting a file.
I guess that can come later.
Alright. Will do music in another time.
Title: Start writing. A title will come naturally once you find the theme of the game, I think.
You're probably right. Seeing as I now have virtually a lot of free time (though without the laptop), I can focus on the script more.
I'm sure I could think of a better name than that.[/list]
Well, I'm still all ears. When you get an idea, shoot.
Speaking of script, you might want to decide how you're popping people into the party. Choose at the beginning, then they'll join you through the game, or all at once at the beginning? Advance through the game, meet them do their quest, then decide then?
As I've said in the first post, you choose the three idols you want to accompany you. You can not interact with any of the selected until you've met them in certain parts of the plot, unlike those who you did not choose, where you'll meet them sometime after meeting your first idol. I'll explain later on making a rough draft of the plot sequence.
