Video games have always been about evolution to me.
I grew up in the NES days (I can't even remember a time without video games...). Obviously I had tons of fun with my NES, but when the SNES came out I couldn't wait to get it. It was so different. Sure the basics were the same, but there was so much added. Bigger worlds, story-lines. The graphics were better, just for the backgrounds. Video games became more alive on the SNES. Then when the N64 came out, I couldn't wait to get one. Mario 64 was amazing. It was an actual world. It wasn't 2D Mario going from one end of the level to the other, it was a full 3D video game world. Mario was alive now, he lived in his own world. When PS2/Gamecube came out, I really didn't care that much. I thought it was nice looking, but it was the same thing on my N64. Now Mario has a waterpack. There was no evolution. It was like putting on glasses, sure everything looks better / but your seeing the same things you saw before.
Enter the Revolution controler. Things have changed again. With the add-on shell controler things can stay the same, but with the new "magic wand" things are going to be totally new and refreshing. Video games have evolved again, and I personally cannot wait to get my hands on this thing and shoot up some Metroids. It's going to be awesome.
