Didn't ffg do a space hulk card game?
Privateer press does a game i find scratches my space hulk itch called Level 7 omega protocol. I'm greedily awaiting my delivery of imperial assault but between those two games GW can reprint the same old space hulk all they like.
I've heard very good things about Level & Omega, with many people saying it surpasses SH
But that's kind of my point - GW had a 20 year head start with a sci-fi dungeon crawler miniatures game that even to this day micturates over most, if not all of it's competition, but can they be bothered to really do anything with it? Heck you aren't even allowed to play it in GW stores.
If it's really that much of a burden for GW to support one of their most iconic and best-loved games, why don't they relieve themselves of that burden - licence the game and collect a cheque every quarter for doing nothing
