to those saying that as people get older they move away from shallow Master Chief and go back toward substance-filled Mario: I think we see this trend more because people want to play something fresh or different from what they have been playing for the last few years. Master Chief doesn't really have any more or less substance than Mario, they're just different. Being a Gamecube owner, I honestly don't feel like Nintendo is doing anything extraordinarily different now compared to the prior 30 years. Nintendo has been targeting the mainstream market forever. However, this time they marketed their system better and the market happened to think the current gaming model was getting a bit stale. In other words, I don't think the Wii would've done well at all had it come out instead of the GC. The market still wanted higher production values. Now people have thoroughly experienced that, and so people are going back to simplicity and ease of use: more of an arcade style experience. If the Wii thoroughly dominates the market, I'm sure in 10 years people will want their high production values back. So, the movement toward Wii-style games is not from people getting older, it's from people feeling the old gaming model was getting stale. Just as fashion from 15 years ago gets reinvented for the present, so to does gaming.
My Top 5:
Shadow of the Colossus, Metal Gear Solid 3, Shenmue, Skies of Arcadia, Chrono Trigger
My 2 nex-gen systems: PS3 and Wii
Prediction Aug '08: We see the PSP2 released fall '09. Graphically, it's basically the same as the current system. UMD drive ditched and replaced by 4-8gb on board flash memory. Other upgrades: 2nd analog nub, touchscreen, blutooth, motion sensor. Design: Flip-style or slider. Size: Think Iphone. Cost: $199. Will be profitable on day 1.
