Good luck finding it.
FPTs are fun when done well. Hell, all games are fun when done well, so that ain't sayin' much, but the problem is that it's so rare that they're done right. Hostile Waters is probably the only example of a really well-done one I've heard of, and I don't even have that. There are a good number of bad ones I know about, mostly old ones, but the decently-made and popular ones are indeed a diminishing minority.
However, I dunno that the concept is dead. It seems an awful lot to me like some games, particularly the EA sportsclones, are effectively FPTs. After all, you set up the strategy and how the units are going to be deployed, but in the end you're playing as a single unit (switching off between different ones, most of the time, but still one at a time) when you're actually in the whole scrum of things, and have to trust not only that the strategies you decided on at the beginning were good enough to enable a victory, but that you yourself are good enough at "fighting" to give the strategies their punch and carry the day.
And there's a limited degree of that sort of thing in games like FS and so on, too. It's quite simplistic the way they left it, but you're not gonna get very far in the game unless you can throw your wingmen around effectively.
