I have a few...
Anytime I spent with my pet rat, Stara. She was like a daughter to me...
The day I beat Munch's Oddysee and any of my Poke'mon games.
The day Walt moved away (Annoying sun of a gun...always bugging me when I was drawing in school. The teacher always had us sit next to each other!!
)
Being with my friends/family members that like Oddworld as much as I do (Very few of those people...)
