On one hand Reload is a competent remake of the original game. Faithful most of the time, but expands and improves on combat and surrounding systems where appropriate.
On another, however, this 'faithfulness' backfires if you already familiar with either versions of P3. These improvements, are, while welcome, but simply not enough to make the game worth the time. Not only does it barely competes with Persona 5 in terms of gameplay, which is an 8 year old game at this point, but it even misses whole campaigns from P3Fes and P3Portable, which is straight up unforgivable.
A good remake of a good game if you never played it. Not that important to play if you did.
