A year or so later: My change in outlook
Since ceasing VN of the Month, I've been slowly recovering from my years of over-reading VNs, the vast majority of them ones I normally wouldn't have taken an interest in. While I still play VNs regularly, I do so at a slower pace, reading more conventional literature and playing normal games as much as I do them.
I recently began to regain some of my VN stamina (though I will never get back to where I was), and I've found that even the SOL VNs I choose to play are far less stressful than before. It is nice to reconfirm that I truly love VNs, after so many years playing far too many charage threatened to make me hate them.
However, I've also noticed that I am far less tolerant of obvious blunders and poor choices on the part of writers, regardless of genre. When something touches on my pet peeves, I immediately drop the VN, and I lose all urge to play it, often for months after. This was the case with Sorceress Alive and it is also the case with Raillore to Ryakudatsusha (dameningen protagonists with no interesting or redeeming traits are one of my pet peeves).
On the other hand, my stamina for 'sweetness' and 'ichaicha' in a VN has recovered somewhat, and I can play a route in a charage with no troubles... However, I no longer desire to play any routes other than that of my favorite heroine. I used to mechanically run through all the heroines in a VN without hesitation or slowing down, but now I only go for the one or two heroines that interest me, ignoring the others entirely.
This change in my own behavior leaves me somewhat bemused, though I can see where it comes from rationally. I simply got tired of plowing through huge numbers of boring heroines that almost buried the good ones, lol.
