Doesn't the princess give Bonk a kiss in one or more of the games?
If so, they should add another warning for "Beastiality" or "Inter-Species Erotica".
Which all together would look pretty freaking cool:
Warnings for other games:
Final Fight: Violence
Castlevania: Fantasy Violence
Ordyne: Mild Cartoon Violence
Altered Beast: Animated Violence
Bio-Hazard Battle: Mild Fantasy Violence
Bravoman: Cartoon Violence
Dungeon Explorer: Alcohol Reference + Animated Blood + Mild Fantasy Violence
Sonic the Hedgehog: NO WARNING -
not even Comic Mischief. I guess Bonk's the one with 'attitude' now.
Wario's Woods: MILD ANIMATED VIOLENCE!
Dragon's Curse: Mild Fantasy Violence + Use of Tabacco
You don't think they're refering to the kind pig who volunteers his time to help out at the local church do you?
