Absolute Anime

Greetings you all, I'm new to the board, and I have a ques about hack (obviously ).
I'm very sorry if this is a common question, but what is the order to view the series/games in?
From my own thoughts I thought it would be:
Sign 1 - 28 --> .hack games/liminality 1 - 4 --> LotT 1 - 12. Is that correct? Because I watched Sign 28 (Unison) today, and I had the feeling this was no intro to the .hack games (it was a good ending though), but a conclusion of the entire series...

PLEASE NO SPOILERS OF THE GAMES AND LotT (I didn't see them yet)!!!

Uh, thanks I guess... it looks like only Sign, LotT and the games are actually popular. And is Intermezzo before Sign not a bit strange as Mimiru says: "I would have never met [following up with names]"?

Anyway, where can I find more info on the AIBuster, Zero and GU series?

Be warned there will be spoilers there.

Yeah, before you answered I already viewed the GF pages (hence, I'm the same user there (check the FFX MB if you want want). Thanks anyway.
