I do not know how surviving to Day 50 as a boy, a girl and hermaphrodite in one and the same playthrough would be possible without violating the living daylights out of logic. Time travel?
Also, what sort of an achievement would offering one's virginity to this or that significant NPC be if you could offer it to each and every one of them? What is the essence of virginity then after all? The presence of intact hymen / phimosis or some other sort of magical oral or anal barrier? Or does having and loosing virginity have anything to do with first time experience? How many first time experiences can one have in order to satisfy their insatiable hunger for achievements in one playthrough? It's like asking for everything on the menu on one plate: a cuckolding virgin sex expert perfect student teacher's pet horror most popular social moth obedient rebel tits penis vagina wolf cat cow demon angel millionaire rape survivor Phelps Astaire...
The main reason for having unlockable achievements in games, including this one is to sustain a player's level of interest as the game inevitably becomes more and more grindy and repetitive. It's a costless reward for playing a little bit longer or digging deeper, is all. A perfect example of that is 'Producer of Lewd fluids' feat that you get for cumming 50 times in one masturbation session ('Literally buckets' if you cum +100 times in one go). The only reason for a player to keep on clicking the same line of text hundreds of times is to get that feat, as masturbation at the moment is one of the most boring lewd actions that a PC can engage in (no toys and a very limited repertoire of techniques compared to what you can indulge in with human or animal 'partners'). A millionaire? Well done! But what is there to do with all that money? At this stage, the PC is probably not paying anything to Bailey, does not need any paid dancing lessons (why bother with those if you can learn to dance while working as a stripper and earning some in the process?). There is no need to take any horse-riding lessons, other than wanting to experience some farm life without being imprisoned there (and improving your tights if you play as a boy). Their only expenses are cloth replacements or repairs and bus fares, which are in the region of I don't know... less than 50 quid a week?
What I would like to see instead is improving on the narrative discipline, so in-game choices do matter and the game actually progresses somewhere instead of drifting in direction of a timeless and complex sandboxy experience featuring a feat-hunting dress up doll with with all parts replaceable and rules softened so much that player's choices are essentially immaterial and capricious as such. Why bother choosing a gender or even eye colour of your character when you can change these just like that, if you have enough money (which you will easily)? Unless... a sex change operation will cost you that gazillion pounds and months of psychologically impactful pre-op and post-op therapy, which should make a player think twice before they happily resume grinding through another year in the same Town, with the same School and Orphanage, the same robotically unaware NPCs with apparently no agendas of their own outside of their interest in the PC and the same bunch of income sources to choose from.
I'll give you that, I forgot that the exact wording for the feats is to get to day 50. I thought it was to live for 50 days. Hell, maybe technically it even is, I have no idea how the game is programmed, will the feat trigger because this exact day came, or because the game calculated that 50 days passed since the beginning of the game?
I understand that the idea of repeated virginity losing is ridiculous, but even if we had the means, no one was going to force the player to use it. As of now losing virginity means nothing but having a unique line of dialogue and reference in the statistics (btw, I'd lose my shit if I accidentally lost virginity to some muscular man, and only noticed it a month later, it would be an instant restart for me). If I had an opportunity to spend, say, 200 000 pounds to be able to open a feat I normally wouldn't be able to open, I'd gladly cling to it. It's a matter of satisfaction, not game or real life logic. I simply want to see all icons glow at the same time, because dim ones really irritate my eyes, lol. And yes, this 1mil needed to go anyway, so why not trade this immense amount of money you would never use for a sense of achievement.
Not sure why you are so against the idea of changing the character during the game. People in real life tend to change too, they dye their hair (in game we can also do it, but the game will still remember the natural color, and you will always have an opportunity to remove the dye), wear colored contacts (once again, you could always decide to stop wearing them), get artificial tan (tanning beds when? since we already have tanning mechanics which I don't even know works or not, because I've never seen my character get darker skin, despite sunbathing to facilitate cat transformation), some even change sex (even though the change is not perfect; I'm no specialist but I doubt you could slap a working live dick on a girl given current state of our knowledge and technology; however, it's a game we are talking about, and here we have angels, demons, giant creatures scaling rooftops and tentacles assaulting people). Imagine having played for months and still having the same doll but in different clothes. It'll get boring pretty fast. So what's so bad about letting the players change the color of their characters' eyes? Yes, you can always start a new game, but for me it's a pain to start anew simply because I've gotten tired of red eyes, and I want them blue. Sex-wise it's more complicated, and having tools to change your sex in the middle of the game is crude and contrived, I agree, but I'd love to have those tools nontheless. Especially if Vrel could come up with a cool story behind such drastic changes, like rituals or whatnot.
I agree that a more complex approach to players' decisions would - in theory - be great, but I struggle to fathom how it could be achieved in such a way that the game would stay enjoyable, at least for myself. I need a clear-cut example of in-game choices really mattering, because on my own I can only come up with a restrictive strategy of 'If you decided to have A, then you would not have B in this playthrough', and I wouldn't like that. I want to experience storylines of all characters in the same playthrough, be a jack-of-all-trades, date all love interests, and generally have no hard limitations.
