DS would like some new games for his 9th birthday, ideally PS4 but could be Nintendo Switch or PC. He likes Fortnite (obviously), Minecraft and Battlefront. My preference would be for something that is actually for his own age and not too fighty, but I know he won't appreciate a game that seems babyish to him and it is supposed to be a present! Not too worried about the age labels if the content seems okay.
He's quite geeky. Other things he enjoys are card games, comics, maths, Pokémon, Adventure Time, chess...
Any suggestions? Thanks!
