The first thing that really strucks me, is how polite the enemies are. When you're in a street full of fighters, and you're fighting one guy, the other guys will wait untill you're finished to have a go at you. FIGHT ME, but await you're turn. Hilarious!
It was an big improvement to the first game and I noticed that the graphics went through several changes. The sprites looked bigger, along with strong colour palettes, and you'll recognised the huge differences within the colour schemes from the previous game. Plus it cannot get any better as it finally rans at 60fps, making it more fluid than ever.
Something just clicked for me the minute I started playing it. It was like playing a game that I would have designed if that was my job. I couldnt fault it.
