I uh, concur
When I bought my NES, the first 3 games I bought with the system (Aside from Super Mario/Duck hunt that came bundled), were Contra, Jackal and Metal Gear.
Funny thing is, the reason I ever owned a NES, was because my brother at the time collected Gi Joe Comics and on the back would see the adds for Metal Gear, and wasnt sure what it was but looked cool, and so bought the system.
It was all about Capcom for me. Megaman and Rescue Rangers! I do have fond memories of Dragon Warrior 3, Teenage Mutant Ninja Turtles 2, and Castlevania 3, though. And the versus mode in Trojan was kind of like a very early Soul Calibur...
I only had Dragon Warrior 1 and loved it.
I had TMNT 1 but never liked it much, but I loved the 2nd one, but never owned it.
Also had Castlevania 2, never owned the others.
And Trojan goes on without saying, one of the best Arcade games of all time IMHO.
