Once, when I was younger, I named a character after a girl I had a crush on... I was playing FFXIII, and Squall was renamed Deano (obvious reasons) and Rinoa was names after this girl... Well, was quite fun watching the characters get closer, as I myself got closer with this lass... Unfortunately things went badly in real life, and due to adolescant angst, and teenage emotions, I couldn't carry on that game! And I couldn't be bothered to restart... (I was pretty far through!) and so I haven't played it since... Been meaning to get it again, and play through now I have no memory of it, but haven't found the means...
Massive shame... From that event I now don't rename any character unless it falls into one of 2 catagories:
1. Its the main Character... Then it gets renamed Deano, (Deanne if Female...)
2. The original name is too complicated, or I cant say it when pronouncing it out loud... Then it gets nicknamed, or names after a similar character from another game!
