Congrats on getting that sucka finished Josh!
Clearly an ordeal, so I'm very happy that you got it done.
My overall reaction is that this is another fantastic slice of sugary LT goodness and the game is clearly coming along nicely. The whole aesthetic of these videos is Tron-meets-Freelancer, and I'm loving how things are clearly evolving each time whilst showing solid progress towards the final result. In other words: I'm green with envy, as usual.
Some more specific thoughts...
Warp rails look great! There's a real sensation of speed, which I don't think Freelancer captured as well. I actually liked the futuristic, vaguely magical look; if felt like we really had upgraded the mechanic from Freelancer in a sensible manner. I also like the particle effects that accompany someone exiting the rail. I was amazed to see some rails that didn't appear to be on the ecliptic too! Man I've been asking about that for a while, and they just appeared - or that's how it appeared to me... One thing: when drawing the system map, straight lines that join the nodes would be useful I think (toggle-able of course!).
Market interface looks polished and functional. Flat's comment about increasing prices being counter-intuitive also struck me; I wonder how much this is because we're not used to dealing with an open market, instead buying from vendors that only have to clear the price they bought it for?
This is right at the edge of my economics competence and needs more thought.
I also wondered about the comparison functionality; in my view this is where a bit of
Tuftian thought would come in handy. Numerical comparison is nearly always better done in a chart; it's a question of data/ink ratio and what the eye can take in. In this case, a bar chart would serve fantastically, as well as adding some nice splashes of colour. Sorting on each attribute when then be really useful, since you can visually see the trade-offs you may be making.
Last point on the market interface - have you thought about
sparklines? They could be a really useful addition to the interface as it stands. Also, now that I've seen it, I really think that a
trade route planning UI would be a nice and natural extension.
Finally regarding the font stuff - I would LOVE to see signs on the warp rails! Specifically signs alongside each node that you actually fly past, just to remind you of where you're going (and possibly from!). More than once I actually went the wrong way in Freelancer; with the exit mechanic this could be addressed much faster in LT.
Aces. Now get some sleep!
