Artwork: pretty good (all black and white).
Caeron 3000 is basically OSR (D&D) space fantasy.
It has the character sheet (2 page), world map & other sheets with a sample scenario at the back.
There are other OSR sci-fi RPGs: Star Without Numbers (£11.99 - Core, or the free edition), Hulks & Horrors (£8.99) for example.
I believe Dragonstar would also be among the list as well.
Apart from the 2 reviews here, there are no other reviews of any kind on any other RPG sites.
The website (caeron3000.com) is non-existent.
Magiqueproductions.com is barely working; only the Home & Contact are working, and have no mention of Caeron 3000.
It's as if they've just tucked it under the carpet and forgotten it.
The only colour is the front & back covers.
At £4.50, it doesn't seem too bad (some support from the publisher would be nice).
