I only really game when I have a new game to play, but once finished I seldom play it again unless it's really good or offers alternative narrative paths. Witcher 3 is the first game in years that has kept me busy for so long, but usually it's 2 days of gaming and then nothing for a long time until the next game comes along. I don't regret any time I spend on it, it is probably my favourite thing in life and I don't even feel bad about that.
