Is playing computer games an unwholesome activity?

Recently I've slipped back into playing computers games. This morning I had a moment of clarity and realised that for me it is not a good activity and I've uninstalled them and I feel a lot better. But generally from a Buddhist perspective is playing computer games an unwholesome activity? If so what aspects of it make it so. Or could one be a committed practitioner and still do a bit of gaming on the side. I appreciate we have discussed the impacts on violent games on Karma before but I would like to know if computer games of any description are unwholesome. (Note - I'm not looking for my own computer game playing habit to be legitimatised so I can start it again. I'm satisfied that for me it is something best avoided. I am just wondering if it is something that Buddhists generally should avoid and if any modern teachers have discussed the issue).
