Mega Man was the first Mega Man game I ever played. Whether that was a good thing or not is a matter for debate.
I was drawn to purchase Mega Man due to the general popularity of his character, but the first game in the series just didn't sell it for me. Don't get me wrong: the game is good. But other Mega Man games are just better.
But let's be fair to Mega Man - it was starting from scratch, in a world without updates to iron out the kinks. It started a series which still hasn't died (at the time of writing this, Mega Man 11 is in development) and the game should be credited as a trendsetter and definitely a classic NES game.
But this game has its share of problems, and the first of these is the difficulty. I enjoy challenging games, moreso than cakewalks. I mean, that's why I love NES games so much - they're a refreshing challenge, something to really test my abilities as a gamer. But I enjoy a fair challenge. Many (though not all!) sections of Mega Man are straight up unfair - Yellow Devil and the beginning of the Guts Man stage come to mind - and the lack of passwords or anything of that sort make it really punishing to get a game over.
Though I've read of graphical complaints of Mega Man, I don't really see it. I find Mega Man's graphical style endearing. Admittedly, there are issues with enemy respawn and screen-clipping, but these issues are technical, not graphical.
The controls are probably my biggest issues with the game. Mega Man feels slow and clunky, he jumps too short and falls too fast. The movement is tiresome, troublesome, and overall contributes to the frustrating difficulty of the game.
Now that we've reopened the games old sores, let's see what it did right. I've already mentioned that I find the graphical style endearing; this applies especially to the character and enemy design. Though the majority of its characters and bosses are simple, they hold a certain charm that defies criticism. The game also has a great 8-bit soundtrack. Elec Man's stage is a particular favorite of mine. Also, the sections of the game which were not frustratingly unfair were a very good challenge that was rewarding to complete. The sense of progression as you gain more powers after every boss is a quality of the Mega Man series which few can emulate correctly.
Mega Man is flawed but an enjoyable experience. I definitely do not regret playing it because it introduced me to the rest of the series, especially 2 and 3, which are my favorites so far. Though it may pale in comparison to its successors, it laid the foundation for a fantastic series; it definitely deserves its spot as one of the great classics of the NES era.
It could've been better, but I liked it. 3/5.
