I just got back from the mall, and experienced the Wii for the first time. I was only able to play Excite Truck, and despite the games lack of features and online play, I had a blast. Never before on a console have I had so much fun in a racing game. It blew my socks off. The controls were so precise, easy and fun, not at all gimmicky or cheap. I couldn't believe it. Even my dad was enjoying it.
I then saw the Ps3 for the first time, sitting 2 feet away from the Wii. I have to admit, at first the graphics amazed me. But 30 seconds into the game (ironically, it was also some kind of truck racing game) the graphics "Wow" factor wore off and a Boredom factor grew in and I realized this is the same old game I've been playing for the last 12 years.
Don't get me wrong, the Wii's graphics aren't bad, just not comparable to the Ps3, but it more then makes up for it in gameplay and fun, thats why I truly believe the Wii will wiin.
