To this day, the Triple Triad music is seared into my brain. I think I may have spent more time playing Triple Triad than actually playing the game, back in the day.
That doesn't mean the same will hold true in this Let's Play, my attitude towards that kind of collectible/minigame has shifted over times, but damn I was into Triple Triad as a kid.
Of all my youthful dead-ended wasted time playing these games, that's probably something I regret wasting time on in final fantasy the most.
Not trying to get a full set of 'Master Materia', or leveling up to L99 in FF7/9, or all the
other stuff in FF8 (Like doing a no-level up run, until disc 3/4, to maximize stat boosts, or drawing all the magic, or 'optimizing' GF ability lists to synergize better).
But the mindless card accumulation really took me places I shouldn't have gone. The other stuff was goal-directed, but collecting cards just to have items lead to a lot of wasted time that never helped.
Even trying to get 30 enoyle cards in disc 1 (to refine into energy crystals, to refine into pulse ammo, which could let you get LionHeart on disc 1... in theory) was just not worth the time spent, even if I was mindless grinding to max stuff out after school.
Just stick to collecting all the unique cards and enough side-games to break the game (Does not take much to break the game).
Hell, you could probably write a list of 'the top eight ways to break final fantasy 8 over your knee' just using stuff from inside balamb garden.
