Unfortunately, since the source code for Homeworld: Cataclysm has been lost, they couldn't do a remaster of that. However, the emphasis is that these games are remasters. Not remakes or do-overs, but just updates to the games that take some advantage of the hardware we have now, plus some extra doodads like difficulty levels and fixing of old, long-standing bugs. Here's a look at how Homeworld 1 & 2 look now. (First half is Homeworld 1, second is Homeworld 2)
