I agree with this, Sonic I can kind of understand though since Sonic and Tails are very similar in personality to Dash and Twily. The PROBLEM is when we get these Mario and Sonic at the Olympic games (let's be real, Fluttershy and/or Rarity wouldn't really want to compete in those outside of Pony life) crossovers that are just weird MS Paint drawings of EG Rainbow vs Sonic/Mario, that's where I draw the line. With that said though... I'm not opposed to ponies appearing in crossover pics like pheephole and his Mario Sports pics. (Love those). So in a nutshell fine with crossover pics, just make em look good.
