You should finish it.
There are a lot of bugs in this thing. I didn't really mind the ability to cheat with the relationship points considering the girls were hard to find. I got to the girlfriend level with Quistis, Rinoa, and Selphie but couldn't do anything when I was in the downtown area. I think the game would play better if the girls had a certain schedual that you could ask them for instead of having to run around randomly hoping to see one. A mini game would be cool to break up the monotony of the training and work.
Graphics weren't as bad as a lot of people made them out to be.
