For those born sometime between 1980 and 1990, this'll make your day. If not, viewing it will be a waste of your time.
It's a role-playing parody, mostly taken from the Final Fantasy series but with a touch of Zelda as well. While VII is the primary focus of the satirization, the creator goes back as far as IV (from what I can tell--there may be some III in there, too). The timing, the sound effects, and the UCs are hilariously well done. The Chocobo running into the camera is the only aspect of the spoof that should be done away with. Enjoy!
