Hardly the negatives. I can present a reverse Uno card and explain how all of them are actually positives. To be honest, It's not the game's fault or Eva Kiss' fault that you only care about for porn.
1. As I said, it's really personal. I'm here for the story first and I love the plot and deeper characters. The sex scenes are meant to be unsatisfying. I'll tell you why in a minute.
2. Yes, she went for more realism. And Ian is 27, while Lena is 23. Both are responsible adults and care about their health. Truthfully I'm tired of all the unrealistic condomless sex in porn games. Condoms should be more welcomed in regular porn as well. All the testing is not shown on camera so teenagers may get the wrong idea from that. Eva is being a responsible game developer and teaches kids (let's be real, it's easy to access porn for underage teens) that it's important to be prepared. Safety first.
3. That's what's called having a developed protagonist. GGGB was different because Ashley was a clean slate, and you can pretty much define her personality and thoughts yourself. With ORS however, we have defined Ian and Lena, with their own goals, their own dreams, their own personalities. Think of The Witcher for example. You can't define his thoughts, you can only say different things and choose different actions. But all of those options are based on Geralt's personality. Same here. Choosing to sleep with other people felt wrong for them because they're destined to be together. It's their Red String that cockblocks them, hinting that it's not what they're supposed to be doing, and instead, focus on each other.
4. As I said, it's just you. Didn't feel anything off with the pacing. The storytelling was tight. If it was even more rushed, all the character development would've gone to the toilet. Not a single line is felt like a filler. Everything was either for character development or setups for future story developments.
