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)!!!
