I totally understand why you guys wouldn't want to make a 3D version of the game. All of the art done for the game would be useless, and I know that a lot of hard work went into it. Lots of original media would be required for such a thing. Such a thing wouldn't be at all feasible if you were starting from scratch. However, I'm very good at what I do - I can model, and I have a TON of RPG type 3D stock media. Lots of media that I use in Geisha House, for example, can simply be re-textured for vastly different looking models and characters.
If you released an impressive looking video of a 3D game, people (and talent) would flock to it. It seemed to have a tremendous support base early on. I think that people would appreciate a well made 3D version of a game that they love. I won't make 2D games - I grew up with 2D games and I absolutely love them, I have tons of older 2D games that I play when I need to take a 3D break - but so much media is required, so much pixel art. The worst thing is that the media isn't portable. If your 'Creative Director' wants to up the resolution, you have to start over. For 3D it's much simpler, every model is portable to any other project. Animation is easier, once you've created the model all you have to do is rig and animate the bone structure.
I've made 2D type games that were actually 3D confined to two planes of movement. The result is more flexible environments, easier media creation, dynamic lighting, etc.
My interest is this project is multifaceted. On one hand, I absolutely loved Quest for Glory III, I played it every possible way, maxed out every possible stat, saw every possible ending. I got so good I actually beat that mirror copy of myself near the end. The same thing still happened, but I felt like a badass So, if I were involved in such a project, it would indeed touch a special place in my heart.
On the other hand, I see it as a good opportunity. It's a well known project, it has a large potential fan base, and the subject matter provides us with an entire world and mythology ready to tweak and use. Also, I have no doubt that the game as it is planned is rich and detailed and fantastic. I said that I'd want to keep the option of commercially publishing the game open, however my intent is not to make money. Everyone who was involved in a published game would have a fantastic bullet to add to their resume, myself included. It takes two shipped games to work as a Game Developer, and Geisha House will be only one. It would also popularize my RPG Creator system, which would allow games like this to be created. Geisha House is based on the style of Ultima VII, but this would greatly expand its visibility into a different genre of gaming. That would be sold for profit. The point is that I see the publishing of Hero6 as more of a formality with the intention of making it abandonware in an absurdly short amount of time. The legalities of this could be messy depending on the publisher and the terms of the contract, but anything is possible if it's done right.
Though nostalgic, I'm a very practical guy. I wouldn't dream of coming into a long running project like this and attempt to strong-arm or warp it into something it's not supposed to be. I just think that 3D has so much more potential than 2D - you can make the same game with the same viewpoint, interface, and style of play, but better and easier. You guys that are still involved in this should discuss it and see what you all think. Maybe everyone is dead set to have a 320x240 2D recreation of their favorite game. Maybe some want to see that game that they loved so much recreated in 3D.
If there was any interest, I'd put together a tech demo of a 3D version of the game. I think that the best way to accomplish this is by recreating a memorable QFG moment(s) in the 3D engine, accompanied by some combat. This video, and /or tech demo would provide six months of intense interest, and at that point much more advanced demonstrations of the game will be available.
The only thing that I would have to do is to hire a 3D artist to make the hero in 3D. I prefer to contract out my character modeling, I'm better with non humanoid models. This would be an acceptable investment to me, provided that there was legitimate interest.
You guys talk about it, think about it. AGS is a nice engine, but it is within the realm of possibility to create a game that is far superior to Quest for Glory V, and such a thing cannot be accomplished in 2D.
