I'm not sure how much my copy of d20 Future differs from the ones you guys have, but I figured I'd put a little input in here.
(Translation: Ralts runs his big yap again, and tries to see if he can fit his clod-hoppers in his hamburger eating device)
When I got the d20 Future book, before I opened it, I, personally, was worried that it would NOT be too generic, but instead, would focus on one campaign setting, and based on that setting, would adjust all the power levels accordingly.
Not so, I discovered when I began going through it.
See, I'm looking at it from a slightly different view. Not someone that expects to drop the book on the table and have it toss out PC sheets, maps, a campaign setting, and run a game for me (And no, I'm not accusing anyone here of that, but I have seen that attittude displayed on other boards I lurk around at like a raggedy ghost.) and some lackwit friends.
I'm looking at for how well it supports the "generic feel" of the SRD and MSRD.
I was delighted in the toolkit that Wizards of the Coast had handed me, and I liked the bare-bones feeling of the book.
BUT...
I will concede that I was sightly disappointed. I found a lot of it "unimaginative" as far as Sci-Fi goes, since everything was based, primarily, around one advance. Something I feel will lead to "canon arguements" if a setting has no "graviton generators" but instead uses "tachyon inertia collectors" to power it's technology.
I'm a long time sci-fi reader, and author, and at first, this lack of detail and the rather restrictive technology bothered me. It kind of made the book feel a little flat.
Then I spent the time to read, and reread it, while jotting down notes on photocopied pages and notebook pages, and began to see the books full potential. (It's not like I had anything better to do, I'd had back to back heart attacks within a week, and being restricted to my bed with only the 7 seasons of Friends DVD's, the Alladin VHS movie, and the d20 Modern and d20 Future books. WHEEE!)
What the authors put in there was only ONE possible future timeline. The consideration that ballistic weapons would no longer exist could be a mistake that the population and military thinkers of the timeline were guilty of. The fact that so few power armors, spaceships and vehicles were in there meant I could pull a lot of vehicles and equipment from my own science fiction! Everything in there was only an example of what could/did happen!
So the book had a few flaws? So the data inside of it was skimpy here and there. So what? That meant LOTS of room for those few companies who choose to produce d20 Modern (and now d20 Future) products. I can foresee books of mecha, vehicles, cybernetics, races, creatures, whole PLANETS being detailed.
The book was bareboned.
I think it was the best choice they could have made.
Too much detail stifles creativity.
