I just watched a great video by Egoraptor, about game design and MegaMan. I'm not very much interested in game design and I never played any game of the Megaman series, but this video was both entertaining and interesting:
The video is a whole 19 minutes long, but it's really worth watching it. It also shows nicely what's wrong with todays games. Now I feel I know a bit better why games back then really simply were fun, compared to the scripted game movies we have to play through today.
