To be honest with you Shee, I've seen several of those on Youtube, and played at least three different parody hacks on ZSNES, and none of them were particularly funny. Most seemed to be the work of 12 year olds who enjoy inserting dirty words into otherwise normal dialog. I'm not really a prude, but Jesus Christ say something funny for a change!
That being said, I was pretty cynical about this to start with and it did nothing but confirm my biases. It just seemed to focus too much on irreverent racial stereotypes and colloquies, rather than actually being funny. I can't really judge the editing, as I'm not a Flash person, but based on what I've seen from others, it seems to me that its overall pretty slipshod.
That Chrono Trigger Unglued though was awesome. Its probably the only CT parody I enjoyed.
