I like it when games let you min/max to absurdities. Breaking games if fun, but it's even more fun if the developers saw it coming and can still throw out monsters to smurf with you. And I don't mean the optional kind either, which had better be able to stand up us. I mean plot-related monsters that adapt to you're strategies.

But more than that, I like that moment right after you get the full party and you go to the airship/hidden base/End of Time and see them all there. It's great. And on the party select screen when there are blanks and seeing all those filed in, I love it. Especially in games that force you into parties in the beginning.

Like that moment in FFXIII, sure it's almost everyone's favorite moment, but for different reasons and mine is because I can finally wreck trout with Fang, Snow, and Vanille. Or in FFIX when you get on the boat about halfway through Disc 2. I mean sure you're still missing Eiko and Amarant, but it's the first time you get to select your party. Or in FFVII when you leave Midgard.
