Hello and thankyou for taking the time to leave such a detailed comment. I will take all of these on board.
I could add some more nationalities, the ones in game I have based on where the majority of real riders are from.
Staff signing is something on my to do list, so this will be more based on team rating & class etc
Scouting is limited as you only have one team scout. I could look into maybe having more than 1?
Rider market sorting/searching is something that I agree needs some work
ADWS to move around the screen, O&P (or mouse wheel) to zoom in/out (you may have already found this out?)
A user guide on playing the game is something I am working on and will be included in the game when complete.
I am glad you enjoy the game, you're right it is a demo, and hopefully any changes & additions I make going forward are well received.
