Why we think it should be on the Virtual Console:
Capcom's Trojan is like two games in one: both fairly well-made, but not really fun. The first part-- the main game-- is a side-scrolling brawler in which you, as the eponymous Trojan, walk around a post-apocalyptic city in some severe red boots, slashin' at some random dudes with a sword. You have a shield that allows you to block bullets and stabby attacks, so the regular enemies aren't much of a problem. Then you get to the end of the level, and face a boss who, in classic 8-bit tradition, follows a predictable pattern. Unfortunately the pattern is "it hits you a bunch of times, and then you die." Most likely you'll play through a couple of rounds and give up forever.
About halfway into each level, there's a manhole to drop into and fight an optional boss. Your reward is a temporary jump power-up. These battles feel almost like an early fighting game! The level bosses do too, but they're often in pairs and thus lose the one-on-one aspect. We wonder what all these tough fighters are doing in the sewer? Is the sewer a desirable place to hang out?

In fact, it pretty much is an early fighting game. This is made more explicit by the two-player vs. mode, in which two identical Trojan-guys face off using the normal game's battle engine. Both players have a sword and shield, and hack away at each other until one's life bar is empty. The matches are best-of-three.
And this is where most Trojan game time is spent; stabbing and blocking. It's always fascinating to see a pre-Street Fighter II fighting game, and this one is significantly more fun to play than Karate Champ or the horrible Urban Champion. Or, for that matter, the original Street Fighter.
