Megacraft Classic is pretty much the definitive Mega Man-themed Minecraft resource pack by this point, mainly due to lack of competition. I'm so lonely. =(
If you love it, could you view one of these three other places where it's hosted? Talk to me about it in the comments and leave likes; they let me know my work is appreciated.
I'm the author of the book series "Tales from the Creature Keeper", and in this video series I seek to recreate the settings from my books in Minecraft. The series is named after the town of Timber River, the main setting where most of the action takes place, and you can learn more about it from the books themselves, which are available on Amazon and Smashwords.
Freedom Planet is a game by GalaxyTrail that calls back to Gunstar Heroes, Rocket Knight Adventures, Mega Man, Pulseman, and even Sonic the Hedgehog. The main reason I love it is because it's better than pretty much every modern Sonic game ever made while also being very respectable in its own right.
