Shock Troopers: I have been after this for a while but I didn't want to spend too much. I found it at an arcade and got it for $30. Such a badass game. Like metal slug, the unique enemy animations (guy smoking, etc) are great. Love those little details.
Shock Troopers 2nd: Bought here from gegrago (awesome seller). I have a soft spot for pre rendered sprite work. It's a shame there just isn't as much bells and whistles as the original. The gameplay is still there though. Way more violent so it gets points there.
Double Dragon: also bought from gegrago. I really only wanted it because I love the unique neo fighters and this was the last one on my "get" list. The super meter integrated in the life bar is very interesting. Great, huge sprites. I was enjoying it so much that it made me watch the movie on Netflix. I regret nothing. Scott Wolf probably regrets it. Not me.
Viewpoint: bought at the same arcade I got ST. One of my better bargains as it is a beautiful, original copy with seal intact and original label. Only 30$. They guy wanted $100 per metal slug boot, and they were nearly all boots, 1-"6". Gotta love arcade ops and their "earners". Viewpoint is silly difficult and I'm determined to get a good score.
Those are mine, what's yours?
