Welp, I've got too much going on to come up with decent hints for all my games between #34 and #23, so here are the ones I already had a hint in mind for.
#32: After you kill both his birdie buddies, the elephant won't put up much of a fight.
#27: Who's going to judge me for my lack of underpants when I can blow up everyone's face with a critically endangered animal?
#25: I actually think a county, country or a big-ass world would've all been perfectly acceptable next steps for this series.
#23: This game was received more favorably than another game in the same franchise that was released thirteen years later, and a spin-off game from a rival franchise that released on the same year, but not as well as a JRPG that was released two years later, or an action-adventure game that was released five years later. All of the games I've mentioned feature a common gameplay mechanic/plot device.
