Yo, I'm conceptualizing a little FF7 prequel thing I've wanted to make for a while now, and this question is pretty relevant to it. How Tifa met Barret is one of the bits of FF7 lore that has been strangely glossed over up to now. Do you think it was after he formed AVALANCHE? Before? Seventh heaven was seemingly always the base of operation, but going by crisis core some random guy is the the who actually built it, so Tifa may not have always been the owner. Should I just wait and see if the remake addresses this at all? Probably.
