Alright, I'm not going to lie -- I really like seeing people take their own spin on characters or artwork. For example, while not exactly a brony myself, I spent way longer than any grown man should browsing the My Little Pony video game crossovers.
Naturally, when I heard that someone took 375 video game characters and gave them the Mega Man treatment, I was intrigued. I did not, however, guess that I would spend a full hour pouring through all of them to see how many I could name (about 340, by the way) and which ones were missing.
You can find the full image composed by one Chris Bringhurst here. He's also got a good-sized poster up for sale on Etsy as well as a contest to win a poster if you can come up with a classic character he neglected to include.
