I wont classify "___ga" magic to be top-leveled. Intermediate leveled, yes. Top leveled, no. Magics like Meltdown, Ultima and the likes of them are considered "Top leveled", for me at least.
Anyways, I wont ever complete FFVIII (and Im reluctant to do so for FFX, even though Im just left with Braska's Final Aeons to defeat, mainly because FFX's side quest bore the hell out of me), not now, nor in the future.
