I have played this game for over 50 hours now, and it is a solitaire game. I usually play card builders, RPGs, FPSs, and strategy games. This game is not just a simple solitaire game though. It has an adventure plot and is a card builder/battler. There is a lot of strategies. You do battle with enemies using a variety of weapons and thrown distractions. There are tons of weapons, gear, and uniform items to unlock. I played it through once on normal difficulty. After awhile I came back to it and I am 75% through on hard difficulty. When I am done, I can replay again on hard, with all the extra gear I have collected, to go back and pick up some stars I missed along the ways. Sure, it is not eternally replayable, but I already have 50 hours into it and expect I will get at least another 20 out of it. For such a low price, it really is a good value.
