Seelas said: I guess it depends upon your definition of an ExII perfect game. The Protect Ring technically isn't a missable or limited item; you can get an indefinite number of them by playing Chocobo Hot and Cold (albeit at 50,000 points apiece). So the question is whether finishing the quest leaves a paper trail. If you beat Deathguise without completing the quest and there's some sign that you never beat it - a piece of dialogue that changes or something - then it's compromising the ExII perfect game. But if there isn't... well, your save would be indistinguishable from an *actual* ExII perfect game, so who's to say? If you actually have to return to Lindblum after all of those events, then I'm not sure a legit ExII perfect game is possible anymore. The writer of the guide on gamefaqs has a target time of 11:31, which is not a theoretically perfect time. But even allowing for an extra 10-20 minutes...that is a lot of running out of an encounter-dense final dungeon to Lindblum and back again. It seems like easily an extra hour or more, but it would have to be tested.
