Sci-fi version of PQ: Challenge of the Warlords. So if you liked that, you probably will like this. I think the sci-fi aspect is not as interesting. It's not really that different though and I found it kind of frustrating and seemed like the computer was cheating at times. I gave up after a few hours as I thought it was too addicting but no payoff. You just keep thinking, one more, and then you have another generic thing to do. Someone could probably make a great game based on this gameplay but this isn't it.
