Here's the issue. On my old 60GB 360, there were a few accounts. One had most arcade games on, but there were a couple of others with lots of money spent on arcade games. Now I've migrated the data to the new 360. However, despite using license transfer on all accounts, only the gamertag that made game purchases can access the full games. On my old console, my main gamertag I use now could access full games from other accounts because it was licensed to the console. Now I'm left feeling like I've been mugged. Please don't tell me the content being able to be shared across all accounts is locked to my old 360.
If that's the case, it's a pretty horrible practice on Microsoft's part. I pay for games, and I should be rewarded for upgrading to their new console. Not have what I paid Microsoft for taken away from me. It's like going to your car dealer, being persuaded to upgrade to a new vehicle, and then the next morning finding that your dealer's removed the wheels.
