FFVII is my shit, I've played that so many times but its mostly because it was my first FF , when it came out.
I always hated KotR to be honest, summons were just a pain in the ass but at least they maintained their usefulness.
My favorite materia combo is Deathblow + Slash-All leveled up only to 4x slash (the one right before Flash, since Flash doesnt work on bosses.) This gives you a chance for a critical hit in addition to 4x slashes.
My preferred team until Aeris dies, is Aeris, Yuffie & Cloud. When Aeris dies, I swap her with Tifa. As it should be. Yuffie & Cid's dialogue is fucking essential to the game lmfao, having them in my party makes me actually laugh out loud
Tifa's limit break is OK, i can usually land all crits. It's her ultimate weapon that sucks. Ultra power with low HP, that's gay.
Vincent is a shit character and even more annoying in battle. Yes he has a long-range weapon, but so does Barret and Yuffie (superior characters). His dialogue is non-existent and when its there, it sucks or its like Squall. His limit break is absolute faggot city. Faggot ass character
