The rocky start of an amazing franchise
Mega Man went on to become one of my favorite video game franchises of all time, but it wasn't all fine and dandy when it first came out. The first game in the series didn't allow you to save your progress or pick up any type of password. You had to beat the game in just one sittin, and the game was really hard.
The idea was set, an action-platformer where you have challenging levels and shoot blasts from your arm. With other robots as bosses, who after you defeat them you get their power, and each of them have a weakness to the weapon of another boss. Plus, you can choose the order of the levels you go to. That's all nice. The harsh performance in some parts, demolishing the frames, took some magic away from the game as well, being a reflex based game in most of the time. But you can call it a classic, being the blueprint for what came after.
