Mega Man 10 stays true to his franchise.
After that, you will have to fight each one again to finally reach Dr.Willy.
This is a simple platformer game. The controls are very simple: you shoot, you jump and you proceed to the right.
The music is a classic 8 bit, which is very animated, but can annoy some other people.
The game can be played on a "Easy" mode, which is hard. I would recommend you to play on Easy to learn how to kill the bosses, and then, and only then try it on a harder difficulty. Note that you can also save after defeating each boss. The game takes about 3 hours to complete (of continuous gameplay), but in real time it is closer to 8 hours if you die sometimes and need to restart some of the level because you ran out of lives.
This is a classic Mega Man game and needs to be played for any fans of the franchise. For newcomers, this is probably your best bet to get started with Mega Man, considering the fact that you can lower the difficulty and save.
