I like a lot of these ideas! But for an animorphs game, I'm hoping to stay true to the books as far as possible with the game. It's been quite a few years since last time I read the books and should definitely re-read them. In the mean time, help me through
Noelle, thank you for offering to help out with a storyboard. I could use one later.
Noelle: can we have customizable characters
We can do with our characters whatever we want, so yeah.
Noelle: giving characters different powers & team strategies
The characters having different abilities is a good idea. I don't know about the powers yet. The character abilities could give the player a slight advantage in selecting the right characters for the right tasks, but if possible I would not want to force single solutions to situations. Jake could be more agile than others, cassie could be easier with animals and tobias could scout around. And then we have the morphs which will give more advantages. Depending on the choices the puzzles and combat could become easier or more difficult for the player, but never impossible. As for acquiring animal dna through combat, should probably be an option. But not a requirement.
Noelle: levels, inventory and saving
I don't dare talking about levels yet. The inventory drop sounds like a bad idea, see my reply at yunyun earlier. And saving, well, losing a lot of progress because one of the main characters died is a big frustration we want to avoid. Checkpoints where the player quickly recovers could be a solution here, but that would also dictate more linear gameplay. Tt does sound like a good idea and might fit the game.
Aquilai: morphs getting around too easily
Well, tobias might get around easily as a hawk, but that doesn't mean he can get everything done (like muscle-work or some stealthy situations). Especially if we don't give every character every morph (technically, that would also be a nightmare for the one who wants to do the graphics). Some controllers could also become suspicious of birds, which means some areas are out of reach even for that morph.
Aquilai: the animorphs cannot be seen morphing
Yeah, even in populated areas you don't know who's a controller and who isn't. The player should be well informed about this. And given the "who's the controller" situation, sounds like there is room for some detective work in the game. That might be interesting.
Aquila: stealth and line of sight
Hehe, sounds like metal gear. But I have been thinking the same thing, a visible LOS is a good idea. Though LOS should only be visible in hostile environments perhaps, since a visible LOS for a human would implicate that that human is an enemy. Combined with the idea that in the game not every human should be a controller, we get a lot of room for interesting gameplay.
I always liked the concept of stealth in games. Also sandboxes, giving the player room for choice. Not using fixed systems, like a specific combat system. I'm tempted not to think about the game in terms of combat and puzzles. More like dealing with different entities (animals, humans, controllers), which can have different behaviors. Battles are an option, perhaps sometimes inevitable. But there might be more subtle alternatives. Here's a thought: what if the game isn't about puzzles and battles, but rather about terrain and individuals (both friendly and non-friendly)? There are tasks at hand, the goal and destination is known. The path and whom you meet along the path are the challenges. And more than one way to advance along the path. Get the key to a door, or try getting through the backdoor. Are some of the more dangerous animals worth facing to get their morph? It's a challenge and might make a later challenge easier (overpower the enemy). But even though the more subtle alternative is way more work, it might just be more your style of dealing with the situation. This kind of game would be very A.I. driven instead of hard-scripted scenarios. My challenge would be letting the A.I. make sense. They wouldn't notice a bug quickly. And you wouldn't be worried if a single controller notices you as an elephant, it would probably be part of your strategy. The goals and perhaps parts of the story would of course be scripted. Just not the path to the next goal. How does that sound?
