First off, I only played the remastered version on the PS4 and have never played the PSP version, at first I thought I wasn't going to like the game but after playing it I got so immersed by it's charm and rhythm based combat with some lite RPG mechanics when it comes to weapon crafting and battle preparations, as I played more and more of the game's story mode I did notice some problems tho, things that should have been fixed especially in the "remastered" version of the game, like the lack of auto saves during the entire game and some of the soldiers won't pick up items when they walk past them after the battle has been won, I lost countless hours losing progress due to a blackout and some of my best soldiers and items during my playthrough and quest to platinum the game but it didn't affect my enjoyment of the game and I highly recommend people to give this classic a try.
P.S Why was this just a remastered of one paragon game and not the whole trilogy? This game is only 400+ MB and if the other games were included, i bet it won't even reach 4GB and I played the physical edition, it's just baffling that they didn't include the whole trilogy in one disc
