Dramatical Murder 1
Hmmm.
It would be very reductive to call this "gay SAO" - simply because it involves an online game at which our protagonist is preternaturally talented and he's surrounded by a harem. It's more a traditional wish fulfilment type show - ZOMG he's the chosen one!!!! - that happens to eventually involve boinking bishounen, I suppose. I'm guessing the dog that turns into a bishounen in the cyber world gets in on the action somehow too?
The main character's design is bafflingly ugly; with his giant bomber jacket and ridiculous leg warmers he looks like something out of a nightmarish vision of the future, like Back To The Future 2 gone wrong. Of course, the show goes to great lengths to tell us he has a sexy voice (really?) which I suppose is enough for fujoshi reared on drama CDs. Then again, none of the character designs are particularly good except for the mysterious Shiva-esque woman, which surely defeats the object of a BL visual novel.
The music is standard low-budget VN adaptation fare; production values are mostly poor except for the "Rhyme" game sequence at the end which is surprisingly dynamic (if overly reliant on rotating CG backgrounds).
I wouldn't say it's a particularly good show, obviously, but it could have been a lot worse.
