I was worried about the complexity of sophont generation ("is the whole thing going to be this complicated?"), but then chargen looked good, robotics and genetics is robust but readable, and I'm mightily encouraged by starship and firearms design.
My thoughts on sophont gen sort of changed when I started porting 2300AD aliens into it.
It wasn't the sophonts that had me worried, it was the mechanics.
I must admit, when I first glanced over the T5 material from Traveller5.com, I wasn't sure that I liked it. My biggest turn-off was the retention of the T4 "roll xD6 under" mechanic. I'm a CT/MT fan through-and-through, so the 2D6 mechanic is thoroughly ingrained in me, and it is my preferred system. The fist-full-o'dice mechanic of T4 (and the bad reviews

) kept me away from that edition. To me it just didn't
feel like what Ye Olde Traveller was supposed be.
But then I started thinking, is it really two D6 that makes it Traveller, or is it the D6 itself that makes it Traveller? So the more I read through the early rules samples and the T5 preview, the more I liked what I saw (atrocious need for editing aside

). The xD6 method had been simplified from its T4 origins, so it didn't appear to be nearly as horrendous any more (despite the fact that it's still not 2D6

).
And then I began to see it: the
feel of Traveller. T5 will still use D6. There will still be random character generation. Comms will still move at the slow speed of jump. The technologies will still be the same. The races seem to be the same. There will still be uncomplicated adventure-class starships. There will still be randomly determined worlds, animals, and encounters to interact with. Off-line play appears to be sufficiently "crunchy" for the gearheads, but actually game-play appears to be streamlined enough for us CT-types. There will still be the elements there that make the game fun to play for all types of Traveller players.
So to me, T5 still feels like Traveller, and I think that this is very critical to its success. Sure there are changes, but I think that the original black-book Traveller is still alive and kicking around in there... and that's a good thing!
