True in some regards, but not all games are giant time-wasters.
For example, I got my (long-term) GF to play through all 3 Mass Effect games recently. While a significant time investment for all 3, that series can be an intense, emotional journey. If you let it happen, you can learn a few things about yourself while playing it. She agreed with this, and is glad she played them.
Likewise, for more co-operative gaming, choose something round-based like a strategy game or a shooter. The GF likes hardcore search-and-destroy on CoD (and murders everyone, she's really good), I hate CoD in general. I prefer Battlefield, she refuses to even try it. I'll show her the light one day =P
