Purely a discussion thread, this has nothing to do with Project: Eternity as a development.
First off, what is Shadowkeeper, DLTCP and NearInfinity? Different modding tools to either enhance or God-mode your game.
I found it very interesting to play around with these whilst me and my friend was playing our Baldur's Gate session. I felt as I was the Dungeon Master (giving the party some disadvantages at some points, some advantages). We didn't have a Thief in our party, so I decided to Multi-Class one of my characters into a Thief (Adding our own personal Lore to it, why and how this was possible).
What I am suggesting is pretty much a DM-Mode in a future installment of a Baldur's Gate-esque game. Where you don't need to edit anything outside of the game (such as Shadowkeeper or DLTCP) but something where you can edit in-game.
Per example, if I were the DM, and 6 posters on this forum where players in the game, I could enhance your experience as a DM. I could call upon monsters, or direct you towards a quest, give you appropriate experience and so on and so forth. Immersing the player's into an even deeper experience.
Another thing me and my friend were going to start (which we never did, Guild Wars 2 took up his time) was a session where he would play the game and I would narrate the story (Skype = Share-Screen is great for this) as well as use Shadowkeeper and DLTCP to effect his game.
Is this something you would like to see in a future RPG?
