In short, Jedi Fallen Order's combat is deeper than it looks. Combos, parries, and counters define the combat experience. For instance, deflecting the blaster shots of Stormtroopers has two parts. You can hold LB down to simply block; when you do, blaster rounds won't hit you, but they'll deflect away. To actually counter them and send them back at your attacker, you have to tap LB at just the right moment in order to parry the shot
The X button handles basic attacks, but if you can land a hit and then time your successive button presses correctly, you'll do a three-hit combo. Alternatively, if you dodge out of the way of an incoming attack with the B button and then strike, you'll earn a counter as well. It's even more fun if you time the LB block on an attack properly. Again, tap it just as the enemy's attack is about to strike you and it opens them up (well, the lower-level Stormtroopers, anyway) for a finisher.
Jedi Fallen Order is in fact structured like the original KOTOR -- that is, with a ship you can do stuff in besides travel to other planets (like talk to your crew or do other little interactive things), noncombat areas where you can talk to NPCs, multiple dialogue options, and the freedom to go back and forth to any planets you've visited -
