Right now the question is "what franchises still do it for me"? None, I'm afraid.
I grew up on Final Fantasy, Metal Gear Solid and Resident Evil. One by one they fell in their own way.
The last year that I was truly exited for gaming (with something resembling child-like glee) was 2005. I had a Gamecube, so I got Resident Evil 4. I also had a PS2 so I got MGS 3.
Then the next generation started. With its brown/ grey military shooters, pandering to the lowest common denominator (dumbing down/ streamlining), DLC bonanza, gimmicky bollocks like Move/ Kinnect/ Wii, shorter singleplayer campaigns and an overall lack of innovation.
Now I am only cautiously interested in certain titles, like BioShock Infinite and Thief 4.
Gaming has gotten big, now it just needs to mature.
