Great entry point, it was my first FF...
It won't be the best FF you'll play, but it has the turn based combat of 1-9 without the pressure of the atr, it doesn't have the overworld map, that you would hate not having in a game once you play a FF that has it, story has its ups and downs but is pretty nice, and auron, you gotta love auron, best samurai since Cyan from FFVI
I'd play VI and IX last, or if you hate ffx, those are the best games in the series and will ruin some of the other games if you play them first, I recommend those for the people who won't play the whole series :x
If you like X, play VIII or XII after, then VII, IX and 1-6
