The September Game Informer came in this week. There was an article comparing how much it would cost to purchase all of the new Skylander Swap Force stuff compared to the Infinity stuff. The difference was around $400 more for the Swap Force set. Of course, they assumed you were going to get very lucky on the power discs. They did mention the dramatic difference in play styles between the two games. At least, it showed they were doing their homework.
The August issue last month was the most anticipated games from E3. Infinity was number 4, I think. I'm not sure why it wasn't number 1...kidding. That is a pretty high rank for a family game in that magazine.
