At first when i started in the AVN community, it wasn't as bad, most of the big ones were tops 4-6 months per release and i only played a select few, so i didn't bother much. Now, i cast my net far wider and try stuff i wouldn't have before in way higher quantity. Most of the time it's mediocre, but every now and then, i get pleasantly surprised. It is to the point that i'm exactly at that point too. Most of the "big" 1+ yr update games i've lost interest in for that exact same reason. You don't remember too much, too long to restart. For example, in my beginnings, the Dik game was one of the few i played. I had a route for all the girls. Fast forward years later plus a laptop change, i only have 1 route. I now consider this game a pain as now it's basically a free roam simulator and i can't skip most of it like dialogue. Same with Ripples, Artemis, Eternum, etc. Games are great, but the excitement isn't what it was anymore for me. Sure a new release is exciting, but after a couple hours to half a day it's done for the year.
I love this 1 month cycle, even if it's 30mins to an hour of content, it stays fresh and with a few of them in the rotation, you often have something new to play.
