Sure we can talk about FusionFall.
(It's an FF forum after all.
And non-FusionFall topics can be discussed in the Off-Topic or Other Games section, etc. by the way.
Well, you used to be able to type your FusionFall name.
(Like I've done with XLR8 147, IRON 147, Player Unbeatable, etc.)
But then came a time when they removed that feature when the game
became free to play. This was probably done to reduce costs by not making
GMs moderate typed names. At the point, you could ONLY use a combination
of supplied names. E.g. names like Blade Xtremestone. (Name combinations that
could be found in the name selector list.)
But after that, people changing their names most likely was done by hacking,
maybe with Cheat Engine.
