I just noticed a new game at MPC today and they're changing their requirements - apparently.
The install now says that you are REQUIRED to install the MyPlayCity toolbar (actually the Ask Toolbar) for IE to play the full games. It's not completely true that the toolbar has to be installed to play but it has to be included in the install!
You do have the option to turn off changing your home page but you can no longer prevent the installation of this toolbar.
It wasn't a major headache for me because I rarely use IE anyway and I could disable it so it wasn't doing anything. However, I was able to uninstall the toolbar (using Revo Uninstaller to get all the hidden bits) and the game continued to play.
This change just happened recently. I just got Mechanicus last week and it didn't have the new rules.
Watch out - it's still circumventable but they are making life a bit more hectic with new rules! They may shoot themselves in the foot, too.
They did that recently. They had a HOG (Elementals) that was at a cost of about $1.00 for 30 days and then free. The SAME game was available for free at Gametop.com in the meantime. Guess where I got MY copy. (evil smiley)
