Some questions about the flexibility of available tools Options

[Vaeloran]

Hi!
I hope there's a good soul who will answer 2 things I was wondering about..

1) I see there are many mods for BG 1/2, but - how come there are no "stand alone" games, totally unrelated to the BG 1/2 plots? Do the current tools require you to start your "game" within the original games? So my question is - can you make your own game, with a starting area and other areas completely from scratch? I mean, without Candlekeep, Irenicus' prison or anything else related to those games?
2 subquestions; can you make a 2nd (or 3rd) start game button with the name of your game on it? (You know - I'm talking about the window when you're prompted to select "Shadows of Amn" or "Throne of Bhaal")
What about the world map? Is it possible to make a custom one?

Is this a difficult task?


2) How difficult would it be to make a script that takes away money from the player when he rests - based on the level of his party? (Cumulative level of the party * a certain factor = gold lost on resting)


Thanks in advance.

Oh no.. I didn't mean a completely new game.. of course I meant to reuse the BG/IWD graphics.. Otherwise, I would not look here for tutorials.
I am just curious how flexible is it.. when I create a new area (with BG graphics and tilesets) how different can it be from anything in the original games?
