If you have access to a Saturn, I highly recommend Shining Force III. It's one of the best strategy RPGs I've ever played. I've been playing through Saiyuki: Journey West on PS1 and it's very similar to Final Fantasy Tactics, with a few twists.

hammer and sickel- A sequel to silent storm
Shin Megami tensai: Devil Survivor- Lot's of replay value as it has 6 different endings and not events can be gotten.

I would call X-COM tactical, but not an RPG, because your characters are so replaceable and have no story to them whatsoever. And except in what seem to me negligible ways, you can't develop them.

That said, I loved the first in the series enormously, not so much the second, and the third least of all.

THIS very much so x9000

Why mention X-Com when Jagged Alliance 2 is already on the list and better in every way?

Oh yeah, I went there. Screw those game-unbalancing psychic powers!

And their perfect night vision!

But the guided missile does allow for some mid-game payback for your army of blond, spikey haired guys.

Pfft. Some of us found the brutal difficulty of X-Com endearing. It prepared us for the total abuse waiting in Terror from the Deep.

I submit to you a youtube video of someone using psychic powers to beat the final mission in 1 FREAKING ROUND:

Brutal difficulty my fanny.

Jagged Alliance 2 is all about the squad tactics with none of the cheese.

The psychic powers suck, but the game atmosphere is unbeatable. At least with the first one. And the combat is perfect.
