The "classic mode" navigation in the game is great, for me. It's nostalgic and it's the smoothest of the control options available in the new game. I think Rand mentioned that one of the reasons for including the mode was to reduce motion sickness for people who are sensitive to that sort of thing, but when moving from node to node, the camera whips around spastically sometimes and seems to defeat that purpose. I showed the game to my girlfriend and after a few nodes she couldn't look at the game anymore because of the vertigo effect.
If the navigation from node to node can't be smoothed out, I wonder if it'd be possible to fade from node to node instead, like the pre-rendered games. I'm not sure if that'd be possible in a realtime 3D game, but it seems like it would be doable to have the game snap to the next node while fading out the image of the previous node... Just a thought.
