My favourite conferences this year were Limited Run games and the PC Show. LR's was adorable and the Q&A was very interesting, and the PC Show was the only live presentation that looked like it was made by actual professionals.
My current ranking is:
1. PC Show
2. Limited Run Games
3. Microsoft
4. Nintendo
5. Bethesda
6. Ubisoft
7. Sony
8. EA
9. Square Enix (utterly forgettable and with some really bad omissions)
