I thought the six inch line was pretty bad for the price they were asking. Sub par sculpt, basically zero articulation, not the most inspiring of poses, very little accessories (MGS2 Snake got his USP, Raiden got his sword and SOCOM, Big Boss got his 1911 and knife, Old Snake has his M4 and knife), very inconsistent paintjob. The only one that really looks great is big boss, great sculpt (love the soviet sneaking suit and the metalic paint), and pose.
MGS2 Snake is the worse. Looks nothing like him. Raiden has this Sonic the Hedgehog hair going on and worse of all, they actually expect us to buy two Old Snake, one with his normal face and one with octomask and both in the exact same pose (just different vest colour) when they could have just included the the octo headsculpt along with old snake.
And I had to go through lots of boxes of figures in my local dealer warehouse to get one set with decent paint. Basically, quite impossible to get a good set from one carton. Got to pick them from a few.
I sold mine for a tiny bit of profit recently. As big of a fan I am, the overall quality just didn't impressed me enough to warrant keeping them.
Raiden 12 inch I really wanted but having seen and touched two in person and both having it fair share of issues, I am not buying anything from Medicom again. Expensive and horrible QC.
