Ugly detail is fine!
Hmmm. How much background info etc is in the book? I might have to go buy the damn thing...
Honestly, most of T20 is rules and there is little background material on the Official Traveller Universe in the book itself.
I picked up d20 Future recently and after reading it, I'm going to sell it. If you want to do hard science fiction, then you do not need any other rulebook than T20. So far the only thing that d20 Future has that T20 doesn't, is better interior artwork. T20 has got a usable vehicle and starship design system with a supporting combat system that allows you to out-of-scale combat (starships vs characters, vehicles vs characters, starships vs vehicles) with a minimum of fuss. T20 has got a working system for creating worlds and their star systems so that players have a place to travel to (which is something that is annoyingly absent from d20 Future). T20 also has a skill set which makes sense (in both d20 SWRPG and d20 Future the skill Computer Use allows you to operate everything from radar to a computer to an extreme range communications laser, which gets pretty unbalanced during play), a creature generation system that is geared to allow the Referee to create something more like an ecology than a random monster, and all this in an accessible (via the web) game background that has existed for over 25 years.
I was disappointed when I began going through d20 Future. The book appears like it was rushed and most of the campaign material was taken from other sources that were owned by WotC. I was able to find shreds of Gamma World (or Omega World from the d20 minigame in Polyhedron), Star Frontiers (the races and the Star Law campaign), Alternity (races and Star*Drive campaign), and a couple of other d20 minigames from Polyhedron (Mecha Crusade and Genetech campaigns, the rules on genetic engineering and mecha) within the book which gives it a patchwork feel - like WotC grabbed anything that was science fiction that they owned the rights to and threw it all together in one book.
Now, with all that being said, in the end its really up to the personal tastes of the individual buying the book. If you like science fiction, I'd recommend T20. If you like science fantasy, I'd recommend d20 Future. "Comparing T20 and d20 Future is like comparing the movie
Deep Impact and
Armageddon", is probably the best descriptive quote I've read about the two systems.
My suggestion is this, just get T20.
