Customizable, no locking, make this game great again. I decided to jump into PSO2 as an old SEGA player from way back. I am not sure if this is a lack of developer support, but most of the key binds are locked. I know this is an old game, but I think in the year 2021 this should be fully customizable by now. I also fear the new open-world version will adopt this same principle. I can only effectively use the Arrow keys, and this game also lacks gaming mouse support which would have helped alleviate some of the issues.

For the mouse at least, I found that if its software normally auto-starts with Windows, I have to close it and restart it using "Run as Administrator" for the game to recognize it; I think it is because of the way that Gameguard works.

@AndrlCh Ok will try and see if that works
