J'avais fait une liste à l'époque mais c'était surtout une liste des changement majeur sur le jeu (genre, 1 seul BR au lieu de 3 DVD, choix des voix, ciblage manuel, etc ...)
Il y a plusieurs trucs qui ont changé au niveau des paramètre de synthèse (cf le topic pour gagner bcp d'exp par exemple) ou encore l'exp de certains monstre (le monstre qui donne le plus d'exp dans le jeu en donnent bcp plus sur PS3 que sur 360)
Sinon j'ai trouvé cette liste incomplète sur un forum :
Only listing game-play differences for PS3
There are 47 Trophies in PS3 version, 46 excluding Platinum compared to 50 Achievements on Xbox 360
The removed trophies are 3 Battle Trophies and 1 Quest
Skill Manual: Dragon Roar chest is now surrounded by Fire
Requires Water Ring, located in Gabriel Celeste's Room on the last floor of the Cave of the Seven Stars
Skill Manual: Sunflare chest is now swapped with Skill Manual: Savage Sparrows chest, which also swapped with Skill Manual: Max Shockwave
Sunflare is now obtainable in the Purgatorium
Savage Sparrows is now obtainable in Cave of the Seven Stars, in Inner Sanctum
Max Shockwave is now obtainable in Cave of the Seven Stars, in B4
Blue Talisman and Sacred Scepter Chests have been swapped
Blue Talisman is now in the Dark chest, requires Light Ring
Sacred Scepter is now in the Ivy chest, requires Wind Ring
Bosses have had an increase in difficulty/improvement in AI (unconfirmed)
There are new chests along with new content in some old chests as well as shifted positions for some chests/harvest/mining points
Some Item Creation recipes have been altered to have more items, thus making their availability later than they were on Xbox 360
Spirit Bow "Darkstriker" - Now requires Darkness Charm
Dragoon Blaster - Now requires 2 Star Rubies
Deadly Cannon - Now requires Ancient Cannon
Fully-Tuned Plate - Now requires Star Sapphire
