Survey ended about a week ago.
Yeah I found it weird but you're right many stores stock it and likely fans will go to the best exclusive deal store.
After Etsu you were kinda left in the dark on Inyouchuu for a while. So you enjoy Aojiru's other games but don't rate any of them higher then Inyouchuu? I'd say some beat Inyouchuu on the weaker games like Etsu. From my understanding you have a real affinity for his art style, then the content adds another layer of enjoyment. I agree much more happier they are making CG games since in a OVA so much can go wrong and they are much shorter lived.
Your 10 years of allegiance sounds very cult like LOL. You say you never doubted it but after ETSU before GOKU... ;)
My history with hentai is varied, since I like a lot of hardcore perverted content so have a array of people I keep tabs on. I like groups like kai-soft and black rainbow with the samin jutsu series to Trois with Monster Park 2. To indie groups like

The inyouchuu Shoku OVA was much better then the games for a long time when I was first into the scene. Tinkerbell's other games and artist hit it off with me more since I preferred their art style. Though some of the none Inoyuhcuu Aojiru games did interest me (Mouryou no Nie) when his art started to change up a little in I think 2010. But his art style in the last few years with Goku has really caught my eye much more. I'd also say that due to the lack of quality content by other producers in this area that has made me more pleased with Tinkerbell over other companies.
