I'm a big fan of action games, in fact that's about the only type of game I really enjoy playing whereas I can't for the life of me get into RPGs. Yet I adore Final Fantasy Tactics and its clones. There's a reason for that that I noticed right away and it's Final Fantasy Tactics being an action game in tactics form. In fact there isn't much tactics going on in FFT, 99% of the time you'll give orders based on instincts and feeling rather than thought. There's a real tactile quality to FFT and it comes from multiple sources: the aesthetics, the small maps and rosters, the brutal "kill or be killed" approach to combat and its overall flow, the powerful spells and abilities, the customization and the grounded and gritty narrative elements.
Where other TRPGs put a stronger emphasis on puzzle-oriented scenarios, FFT likes getting into the thick of it and channel the pugilistic qualities of the battles it illustrates, it's very compelling in that regard, and while it is a simpler and more straightforward game compared to many other TRPGs of that era, I think it works to its advantage. To me it does anyway.
