I just found out another reason why I will need a gold cheat. For some reason, the developers force you to have their pre-designed party companions at first, then later in the game (still relatively early though), you are apparently allowed to buy "mercenaries" which can be added to your party as your own characters that you design.
But the catch is that they are very expensive, starting at 2000 gold each when done early as possible and the prices just keep going up dramatically from there, the later in the game when you decide to purchase one, up to 18000 gold even, is one price I saw quoted. One major problem I have with the party companions is their voice acting, from what I can tell from watching gameplay vids, ranges from bad to just awful ("Linzi") to the point that it would bother me quite a bit.
The bonuses of creating your own party are several to me. I wouldn't have to deal with juvenile, terrible voice acting, and get to design each character how I would want it. So a gold cheat would let me do all this easily, and play the game with 5 characters, all of which I had personally designed (like Icewind Dale)
Or, perhaps there is a companion or two who I decide that I like later in the game, then I could keep the one or two companions I like, and have the rest of my party made up of "mercenaries", my own designed characters.
