For the record, generic response (I did tell Elsa more about this in the PT), I tend to be around once or twice a day, if that, at best. Sometimes only once every other day. Mafia drains a lot from me and I just don't have the energy to constantly devote every second to it--not even in games I am genuinely enjoying.
When I am genuinely enjoying a game, I will put more into it than a comparatively-less-fun-game, but I still have limits. I still want to be doing OTHER things than the game. (For instance, right now I want to spend time with my girlfriend; I'm not because of ~personal gf stuff~, but it's still what I'd PREFER to be doing more than right now.) I still want to be elsewhere, I still want to only spend so much time on the game, before I go elsewhere. There's just too much time/effort to be invested if I were to go all-out on a game and I literally can't do that--not even with the support of a partner like I have here.
There's also a question of whether I SHOULD be around.
I get more productive, useful, actual game content, out of being around for a while, then leaving, and coming back...
...Than I do constantly being around never-ceasingly.
Not only is it because the quality of my content is better (because I'm more refreshed, more able to be clear each and every single time I come back), it's also because it allows others to post things that they otherwise wouldn't get a chance to post. My presence alters the nature of the content being posted at the time I am around; this is one of the reasons why I prefer to post when nobody else is around. Because I like my presence to have minimal effect on the posting of others at the time, but maximum effect on the posts of people AFTER I come in, if that makes sense.
Basically, people who come in and see that I've caught up post differently than people who come in and see that I am actively posting; the former I've found is more valuable than the latter.
So I'm pretty much never around when it's convenient, and while this is partially because of my schedule (I work when people are around and am free when others are either working or asleep), it is also largely by design and an intentional choice I make in every game I play.
