Had a few different games, I found that being beaten up doesn't take away the virgin stat (bar jobs, even after quite a few events). Most likely by design. A bit odd but refreshing.
Straight sex and anal doesn't increase stats when you ask, but all the rest do when you ask (group,blowjob,ect). This was mentioned before but I think the conclusion was that all 'ask' interactions did not raise the sex stats.
Pregnancy is odd. Did you raise the age to when a girl can get pregnant? No virgins that were young got pregnant after months of straight sex (girls around 17-20ish) but the woman from bleach (with the abnormally large boobs, age 28, non-virgin, no milf trait) got pregnant fairly quick. Might just be random chance, but maybe you intended it to be older women get pregnant only?
Also, this could also be random chance, but I never got rydia on a spawn for the 'take a walk'. I did install all the girl packs before I started any games, and also started quite a few games, but it seems like I always stumbled on the same girls (90% of the time the same ones). I looked in the character folder and the .girlsx (or whatever) file is present for rydia. I think some packs didn't have a .girlsx file so I understand that they might not show in game. (The pack that was split up in the top of page four for example.) Every missing girl is in the catacombs, where they're set to spawn.
The biggest thing I'd like to mention is the security system. I interpreted a comment in this thread that you needed multiple girls to secure the brothel as you increase your clientele. Say you have 6 girls on security. An attacked has to go through all six before assaulting a 'worker', or at least until the security number was below 0.
I had 4 girls on security, with a rating of around +80. The message stated "AAA got through 3 out of the 10 attackers who were attacking BBBB before she got....", and then a message stating 'BBBB' was assaulted. So the attackers overran 1 out of the 4 girls on security, and even though the security rating was still positive, proceeded to assault the worker. Basically the other 3 girls did squat while all this happened, except either independently raise (or lower) the security rating on their shift.
I just presumed that the system worked that attackers had to penetrate through every security girl, and/or get the security rank below 0 before proceeding to assault/rape their intended victim.
Thanks for your hard work on this project! This was a pleasant surprise when I stumbled on it today, maybe the stuff I mention is all part of the EX gameplay, I just haven't seen it mentioned anywhere yet. I like the way you do have to have some strategy in how to expand your brothel, as your expenses do rise with the increasing income. You can take a stay small/do more 'under the radar' (gangs,catacombs ect) approach to build up funds before hitting that assault/security escalation, and I found it possible to stay small with a very small group of girls and still not go out of business, although its tricky, you don't want to hit that tipping point where assaults start ramping up! I think the balance is quite good right now and I can't wait to see what other changes you have in store in the next major release that didn't make this version.
