Not personally. There are times when a particular game has been so enjoyable I have raced home from work to play it. But that's about it. Oh yeah and I used to dream about UAVS around the time of MW2 and Black Ops which was weird.
I like to keep everything in balance and it helps to have lots of different interests. I could happily play a video game, read a book, play my guitar, run around a park chasing a ball etc etc
Addictions wise I tend to avoid gambling. I think I would be addicted to that so I stay away. I've got family members with alcohol issues but fortunately I missed that one.
I smoke too much though π€
