While I agree that NTR tag was too vague to tell the user what content he might expect, current tag system is still far from ideal. As others have mentioned, cheating is also is basically the synonym of netorare. Netori is always about MC stealing someone else partner and swinging give me associations of the MC switching partner with a partner from another couple, while netorase giving me association with MC giving their partner to others (Sluttification) without taking someone else partner.
I've often used one site where you can watch anime, and I want to point out what a huge number of tags it has. You can find literally everything you want: maids, demons, angels, catgirls, vampires, samurais, knights, superpowers, psychological etc. And while I'm not that focused on that kind of fine-tuning for anime, in our case it would be really helpful. Just look at the recommendations section, people create threads there every day asking for games with specific things. More tags could make it a lot easier for people to find the specific game they want. And as for adding tags, first of all, the authors themselves add them to the spoiler, you can take them directly from there. Yes, it will all take time, but new games that will appear, will already be marked right. And those games that get updates will get their tags too, if users will be reporting them. Secondly, you could make a tag suggestion system, like in Steam, where people could vote for tags (but not write themselves, so that haters won't abuse it like "game is shit", "protagonist retard")
I'm honestly not very familiar with the situation as to why this is still in limbo. Is it technical difficulty? Or there is some confidence that these vague descriptions are sufficient for a comfortable user experience?
I'm still waiting for the pixel art tag to be added. When I read the discussions about it, I was very disappointed in its absence. As I got from answers that pixel art is 2Dcg and that's why this tag is unnecessary. Yes it is 2Dcg, but there are a lot of games with 2Dcg and pixel art stand out from others by the style. Many people create topics asking to recommend them games with such art style. I'm pretty sure, people would also suggest some other graphic styles, that have popular demand, which will help them find games they're looking for.
By no means, I don't want to seem ungrateful in the eyes of the administration, I just would like to make our beloved site even better and more enjoyable for its users. Thank you for your attention and hope for understanding.
P.S. Sam responded literally 3 minutes before my post was published. But I wouldn't want to delete my post, as I wanted to express this thought a long time ago.
