Same at least until sex happens then I tend to prefer nakedness over erotic looking clothes. As I want to see them titties and ass haha. But yeah like the scene where she was showing off in lingerie to the MC that was my favorite scene in the game and just wanted more of it because how erotic it was.
I'm also 50 / 50 with you there about the first reveal being in game. I think it depends on the render , girl and game tbh. Alot of renders ive seen for most games I don't care much about. But there have been some damn good ones with them being naked or partially and it just made the render all that much better for me and wouldn't have came out as good if they weren't. But if they were a super slow burn character or type of game then I 100% agree it would ruin their first time. So really I think it would be depended on the game and character for me if I want to see it early or wait in game.
This may come as a shock, but I like titties and ass too.
And I agree that scene was great.
Besides Alex being not only our girlfriend but our wing woman too, slowly corrupting the pure and innocent Isa has a certain appeal.

Even if its only in my head.
You make a great point about eh, premature nudity, depending on the game. I agree completely that for a slow burn game, it really matters definitely less so for one where the girls throw themselves at you in the first chapter.
Generally, speaking, I think for a game that tries to tell a story where relationships are important I would want the big reveal to be in-game. Now this can be quicker or slower, we saw the love of my life naked early in this game (to pretend to be on topic) but we're still waiting for Isa. Different circumstances but both make complete sense
