I loved Origin.
Many of us fear what will happen to Bioware Pandemic. EA has a bad track record of aquiring sucessfull studios and gutting/shutting them down after a game does not preform as expected. They also tend to excessivly rush development cycles resulting in buggy and incomplete games.
Thats why I loath EA. Micromanagement of aquired studios that results in their dissolution.
If they would just stick to publising I would have no problem with them. Unfortunatly I dont belive they are capable of bankrolling aquired publishers and letting them work their magic. History tends to repeat itself.
