Same here, no instability nor crashes. I agree the review catches some of my experiences with the game (difficulty, poor check points, some polish needed in the targetting system, and the suit being a sitting duck if you stay too long in that mode), but it managed to grip me nonetheless : Big, impressive battles, cool designs, cool music, reactive controls.
And I disagree on one point with the review : Once you know its weakness and learn to avoid it (ie using it for hit and run attacks and not heavy duty fighting), the firepower of the strike suit is VERY empowering. Standing alone in front of a cruiser and drowning it under a missile swarm, ravaging most of its turrets in the process, is something you'll learn to love.
All in all, SSZ is not a space sim. It's not Freespace. It's an explosion packed action game, and a pretty cool (but difficult) one :)
