Sadly the fantastic puzzle gameplay is let down by massive problems in the RPG game.
The mistakes in the RPG game are numerous and are made worse by how easily they could have been avoided. These vary from UI blunders like your ship continuing to move while you are in menus and no system names on the mini-map. To graphical blunders like the fact that your ship is indistinguishable from enemy ships in everything except engine trail. To simply odd decisions, like not showing alien appearances on first encounters but at random times, I'm meeting new and interesting species,I want to see what they look like. And the list goes on and on.
Most unforgivable is the terrible writing, while the previous game "Challenge of the Warlords" never took itself too seriously, with an orc obsessed with eating everything and a dwarf creating a machine that no one know its purpouse, including the dwarf. Galactrix takes itself seriously, and sadly the writer can't pull it off, Churning out one the most horrendously written sci-fi junk stories I've seen in a long time.
As an RPG the previous game "Challenge of the Warlords" was superior by far. The puzzle aspects of Galactrix are marvelous, shame they are buried in such a badly executed RPG.
For the puzzle lovers and no-one else.
