Just bought the game: Question about tech tree

[Silent Sorrow]

Yep, picked it up recently. Cost me a pretty penny. I hope it's worth it. Ironically, though I'd been eager to get it, once it arrived I let it sit there for a couple of weeks because it's just so damn massive and hard to get into. Not exactly a jump in and play kind of game. Played MOO2 instead.

Er, anyway, here's my question: I haven't a clue how to approach the research portion. My main problem is that the descriptions you get by right-clicking the items are so brief that I really don't have a sense of how the techs all fit in with each other and certainly no idea in what general order to research things. Has anyone done up a research/tech tree information sheet/page where the stuff is laid out, MOO2 style? You know, something where I can read a meaty description of what each item does?
