Well, BG3 can’t make half-decent sex scenes, so nothing really has changed. If Bioware wanted to get edgy they would have, technology be damned. I brought up Fallout earlier that has more mature content then BGs in terms of violence, language and sex. BGs didn’t, because this wasn’t something that story ever called for (speaking in here regarding world as portrayed in BG1&2, not wider forgotten realms media). 18 rated games aren’t a new concept - they were thing back than as well.
Hard disagree. CG porn has gotten to a point where artists who are talented enough can rig very realistic sex animations and program in physiques that make the bodies move fairly naturally, and BG3 is going for a softcore/GoT level of depictions. We're not talking about Virt-A-Mate with full camera controls, looping animations and selectable positions.
Another reason the original Baldur's Gate didn't have sex or nudity, you must understand, was the ability to sell the game, period. I don't know how old you are, but there was a point in time where if you wanted to make sales at all, you had to be able to get your game on a shelf in physical locations, and if you were a developer who was relying on publishers to fund your game development, they expected a return on investment. A game with sex would literally not be sold in stores. Your game would be pulled from shelves, and your company would go bankrupt. The marketplace is no longer like that. You don't have to worry about being able to sell your game in Target to make sales, and the culture taboos around depictions of sex in media are thankfully being eroded. These advances in social progress have been extremely beneficial for many disaffected minority groups, and the fact that we get to romance companions regardless of sex or race is proof of that, when previously games usually were restricted to heteronormative pairings and even restricted romance options from races like dwarves and others.
The inclusion of sex in BG3 is objectively a positive decision.
