3 is just like a cool sequel that enhances the gameplay furthermore, 2 did some stuff with storytelling that no other game has done before. I didnt even know about the whole Raiden thing before playing through it so it caught me offguard aswell
I agree. 3 has the cooler gameplay and TECHNOLOGY with stuff like The End, but I like 2 more as a period piece. Ive only played it 2 years ago but it made me appreciate what a masterpiece of its era it must have been in 2001.
