How on earth "people", or you, can know by advance that a Civ without leaders will have bad taste ? If it's to introduce revolutionnary gameplay and it's well done, then we NEED to get rid of leaders. Crusader Kings is much different from Civ, and not just by not having leaders.
I have argued in the past that the animated voice-acted Resource Sink Leaders were bad for the game and should be discarded.
I still believe that, but I don't argue for it any more, because I am certain I would be wasting my time. Fully animated Leaders is now one of the signature differences between the Civ games and All The Others. I do not believe that the Civ franchise will abandon them unless they have a mind-bogglingly great alternative, and given that the Leaders have worked well for them so far, it would have to be both compelling and economically attractive (like, Dirt Cheap by comparison) to even be considered.
So let's throw out some Alternatives. Here are some of mine for starters, I suspect and ho[e that other Fanatics ot there have some better ones.
1. No Leaders at all. Each Civ is identified and distinguished only by its attributes and historical title, you interact with briefly-animated or still 'diplomats' or 'traders' or generals', all aspects of the Civ are related to the Civ and not any particular ruler.
I think the chance of anything resembling this being adopted are about the same as the chances of the proverbial celluloid cat in Hades. It would, quite simply, be hugely unpopular and feel like the game has regressed to 1990s standards of presentation.
2. Live Actors. Anybody who played Civ 2 remembers, for good or bad, Elvis the Cultural Advisor. I have no idea whether live actors with suitably accurate and appropriate scripts would be cheaper or more expensive than 3D animations with voice actors, but it would require the same amount of research (at least!). On the other hand, it has the potential to be hugely entertaining if done right.
3. 'Generic' animations. As I have argued
ad nauseum elsewhere, an audience room/antechamber where you interact with suitably-costumed animated Minister or Diplomat, with still (sculpture, painting) representations of the Great Leader present in background. This would reduce all Civs to a single animation requirement with elaborate still backgrounds and so potentially much cheaper and easier to do than the current form, and allow, potentially, a change of Great Leaders throughout the game.
Much as I still like the potential for this system, I also admit that many gamers would recognize it as a 'cheap' way of getting the animated Leader. On the other hand, the essential distinction between Civ and all other strategy games (so far), the fully-animated Interface Person, would still be present.
4. Still Art. Anything from historical portraits/paintings/sculpture, etc. to made-for-the-game representations of individual Leaders and other 'personages'. The problem with tis, no matter how well done, is that compared to an animated human face, nothing else has the same degree of Communication to us humans. The first thing a baby can focus o is a human face, even a stylized one. We are programmed for it from birth, basically, and a still portrait just doesn't have the same immediacy and relevance to us that a mobile face and body language have. Another one of Bierce's brick airplanes, ("All the details are correct, the only remaining problems are Basic and Fundamental") it just wont fly compared to some kind of animation.
5. Gamer As Leader - the 'Avatars' of
Humankind. An interesting idea, but to copy another game's system so blatantly is also a Non-Starter.
