I like the interpretation here, Final Fantasy 8 as a mind trip! Looking back I think of it as weird RPG experiment more worthy of a single play through and study...it's less of a play-over-and-over-again masterpiece. You have the removal of weapon and armor shops for the most part (What to spend your money on???), restocking magic like it's a single use item to put in your inventory, buffing summon spells with button presses, a card game of notorious difficulty, not to mention a certain spell combo near the end which gives you limits and shields you from all damage. Plus you can level up to 99 in the very first training area?
As far as RPGs go, it does seem to be rather moody and mental in terms of game-mechanics. Chances are it's the first Final Fantasy to go over the edge and had some influence on FF9 needing to be a "return to the old school form."
