To clarify a few things:
Free-roaming. I read somewhere that any future improvements to Cantr would include a more 'open' world, where characters could travel anywhere. Imagine the way boats are piloted (any direction, any speed, etc) and transfer that ability to characters walking or driving on land. In contrast, the current system is 'node-based', which means that characters leaving a town can only travel on a set, straight path to a choice of nearby towns. They can't leave the path and go exploring, for example. In a 'free-roaming' system, they could.
I don't know exactly how a free-roaming system might work, but it would probably be grid-based. Each square (pixel) would have a small amount of data describing things like 'land type', number and types of animals, perhaps weather, etc, and the location data of characters would be in the form of co-ordinates. Characters would probably be able to build roads - anywhere - and automatically follow them if they choose to, similar to how roads are followed now. Benefits would be the ability to build anything from a solitary hut to a city
anywhere on land. It could probably also lead to realistic farming and hunting, and might even make 'field combat' possible!
Button-based actions. Yeah, that was kinda vague, wasn't it...?

What I meant by that was that we could have various buttons like [Wave], [Frown], [Smile], etc, which, when clicked, would generate that event, automatically translated for all languages. For example, we currently have a [Hit] button, which generates the event "You hit Joe" (and Joe sees "Dave hits you", and others see "Dave hits Joe", etc), and all of this is automatically translated so that, if Joe is Dutch, for example, he sees the event in his own language. The advantage of this idea is that everyone would be able to understand the emotes and actions of everyone else without having to either manually translate them or just use English and hope they understand. The downside is that, at least to begin with, the number of available actions would be quite low, but new actions could be suggested, included and translated all the time.
By the way, I'm all for things like more clothing and tools that improve the game and make it more immersive, etc, but it seems to me that too many of these things could be overwhelming, especially if they have no real impact (for example, clothing is totally cosmetic right now).
Piscator, I'm not talking about Cantr III specifically, but yes, I think a reprogramming of the game from the ground up might be a good thing.
Marol, I hear what you're saying, but couldn't a redesign make maintenance easier? Plus, if the game's better then more programmers might be attracted to work on it.
As I said, these aren't strictly suggestions, more a general wondering-ment and discussion.
