1. Not beating SEGA GT when my DreamCast died, also Gauntlet Legends. Also for playing Shemnue and Sonic Adventure too late in the lifecycle.
2. Buying a Wii vs a xbox 360, realizing that its not really in my taste. (later swapped for arcade model and halo 3)
3. Playing mostly sport games vs FPs's
Above I'm a proud Gran Turismo fan, not a Sony fanboy, and now a proud 360 owner, but sharing xbox live accts ATM
End of 2009 Predictions (made Jan 1, 2009): My predictions were pretty accurate, the 360 was over and the Wii was just under.
Wii: 65 mil (yea I'm crazy) 360: 35 mil (its getting there) PS3: 30 mil (the slim better do well)
End of 2010 Predictions (made Jan 7, 2010):
Wii: 81 mil 360: 47 mil PS3: 45 mil
