Provided it doesn't recreate the magic of the arcade game; Robocop has its own charm on the NES Easier than the G
If you are a classic gamer, from the days before they had a save point every 5 minutes, the difficulty won't make you flinch.
Like the XBox game, there are parts where you will find that repeating the level will endow you with enough knowledge to master the foes you fight; something that was criticized heavily in this and the XBox version, but is the standard for the classic definition of videogame strategy.
Robocop on the Nintendo is easier than both the Game Boy version and the XBox release, combined in my opinion.
I, personally, have completed both this version, and the XBox version, but not the Game Boy version.
You take the role of Robocop, picking up his trademark baby food, as well as battery icons (to increase the time meter, the time limit is not as much of a hassle as is found on other games) on his path to blast away the gangsters who brutally gunned him down in the line of duty.
All of the film elements can be found in this game; from Clarence Boddicker to Dick Jones to the unnamed robber from the convenience store. The only exception being that Anne Lewis doesn't make an appearance.
Robocop's nemesis in the first film, the ED-209, makes an appearance in this game as he does in the Game Boy and XBox releases, and is animated accurately; there is also a strategy to defeating him that one can develop instinctively rather than it always being a seat-of-your-pants operation.
Robocop is a side-scrolling shooter at its best, not limited to the shooting but also including, usually optional, hand-to-hand combat.
The game includes a version of the movie's trademark theme song throughout the levels, and the gun sound and effects (such as Robocop pulling the gun out of his leg holster) mimicks the movie perfectly.
Another side-note is that the manufacturer of this game, Data East, provides several arcade machines in the sequel to the original Robocop film, Robocop 2 (whose game basis was much more difficult than this one)
Inbetween some levels is a shooting sequence similar to that found in the film, in which if you destroy enough targets (which, for repeat players, isn't a difficult task) you receive an extra life (though there is no meter detailing the number of lives left, once your energy meter depletes completely, Robocop will be able to return to his normal functions provided you received an extra life)
There are a virtually infinite amount of continues, therefore it isn't especially hard to complete this game in one sitting (which is absolutely necessary in a game that doesn't include a save system)
The graphics may not compare to the arcade game, and while the arcade game was two-player and this is one-player, most of us certainly don't have hundreds to thousands of dollars that are necessary to purchase the arcade version, and this game stands on its own with its accuracy to the film (it has animated cutscenes that detail your point in the film, making it more of a film-based experience than some of the lesser-accurate videogame depictions of their big-screen predecessors)
I recommend Robocop to fans of the series as it, of course, has better graphics than the Game Boy version, and is indeed easier than both the Game Boy and the XBox versions, and has a certain indescribable charm to it that follows the film well.
Blessed Be
