It reallt doesnt matter what order you play the FFs in. As long as you play X before X-2.

You have 7, X and T. You just emulated 1 and 5. Thats a LOT of gameplay right there. I'd complete each of those before starting in on 8.

Beat 7, it'll take a while but its well worth it. Then move into Tactics. theres minor linking between 7 and T so, that may be the next best to play. After you rule Tactics play out X. That won't take that long, but you can get caught up in the monster creations and area conquests. All in all a good game. Its not neccessary to play X-2 directly after X bacause its not that great of a game. You have 1 and 5, which are both old school. Take 1 first and play that. After going throught 7, T and X you'll realize that this game is definitely different and yet similar. Playing the roots of this series made me love the FF series even more. Once done with 1, play 5 (if at any time you can pick up Origins, Chronicles and Anthology, do so. Warning: DoS is not the original 1 and 2, they are doctored to be like more modern RPGs. IMO they made 1 worse, but 2 better.) After your play through of Tactics you have a great understanding of Job systems and FF5 will not be at all confusing. The game is well done.

After that play whatever game you have next. If you got Origins, play 2. If you got Anthology, Play 6 (and if you are sick of all the FF, Crono Trigger is an awesome game) If you have Chronicles, play FF4.

If you are in the mood, FF8, 9 or X-2 are all still fun games but once you get the old school games and the better of the modern games out of the way it may be downhill. 6 and X-2 aren't my favorites, thats for sure, but like someone said, and you inferred, 8 might be your cup of tea. Actually I think if you want to enjoy 8, play that right after FFT Go 7,T,8,X,1,5 then mix and match the rest.

By the time all of this gameplay is done FF12 will be out and pick that up. I got a good feeling about that game. I've seen trailers and my spine tingles.
