I recently bought FFVII DoC for PS2, and these are my thoughts on it:
Gameplay: Lets compare. FFVII = 40-50hrs, DoC = 2-3hrs And thats on Hard...
Customizability: I love it. FFVII NEEDS THIS LEVEL OF SOPHISTICATED CUSTOMISING!!! You can change: barrel, handle, the bit that shoots/reloads, scope, materia slot, dangly add-on bit ( basically materia )
Content: Poor, there are like 6 Materias available: Fire, Water, Lighting, Speed, Damage, Range ( all gain mp in a weird way )
Movie Sequenses: Love them, Better than advents children, no glitches, lagginess.
Graphics/Smoothness: Good graphics, as for smoothness, lacking, sadly i can make my guy look like hes moonwalking.
Playable Characters: Vincent, Cait Sith.
The Movies are awesome, although, you do see Cloud ( in like 10 second OWNAGE fight move ( flying sword/slash /w lightning blast )) and tifa ( 1 word "Barret!" ) and Barret ( weirdly he says a splurged word that sounds familirly like "yune!" )
