I think one of my favourite things about Astro is how it is steeped in Playstation history.
This is something Nintendo really gets right, have no idea if Xbox do it, but its never been something Sony have focused on. I loved all the constant references, from clouds in the shape of dusalshocks and ps1's, to bots dressed as just about every PS character you can imagine, to more subtle things like pavement stones in the shape of PS1 controller ports.
As someone who has been all in on Playstation since PS1, I really got a kick out of all this Playstation fan service. IMO its a big improvement over 'generic future world with little robots'
