There are four romances:I'm somewhere in Act 2 at the moment. Unlike before, there were a few bugs that started creeping up in the meanwhile. The escape from the "Heist" mission where you have to fight off drones had V spawn without a weapon. As this kind of mission locks you out from pretty much all of the interface, I had to wait till the car got blown up and hope the last checkpoint wasn't too far back. I had a case of Groundhog Day at a slightly earlier point where I had issues with a specific set of NPC's (no boss) I couldn't get past, you weren't allowed to save for ages, and the checkpoint brought you back before a whole scene with dialog and a few actions you had to perform. Bah. Not sure what was wrong there. I even tried to change the difficulty after I got fed up with this. Changing the difficulty forces a reload (last checkpoint), but didn't seem to do much else than change the AI (mostly of the surveillance) slightly, while enemy damage seemed to be completely unchanged. So I'm not sure whether that was a bug or not, as the whole situation seemed off.
Another bug was when V couldn't get out of a crouching position. But other than being forced to talk to crotches, it was just a glitch that solved itself at the quest end. The missions I got in Act2 all felt much easier than the ones from before, but this could also be because the game suddenly started throwing level-ups and perk points at me, plus better armor and weapons. I'm not sure I feel competent to comment on the actual system, because I don't think I feel I have any mastery of it (I went into the game basically blind and had no expectations, but no real system background knowledge, either).
As an aside, I wonder how the crowd that spent most of their pre-release discussions fantasizing about romances in this game feels, btw. I haven't met any yet, although I did quite a few quests with Lucy, and there wasn't anything remotely romantic touched upon (which was fine by me). Out of curiosity, I did this one-off with the corpo woman. Driving there took at least four times as long as the following short cutscene, which wasn't anything remotely interesting, either (not that I expected it to be). I got the first dildo of my game out of this though, and I think it's an epic one (haven't looked at the stats yet)? The way this is treated is such an afterthought that I can see a bit of (ultimately amusing) rage in the future, as soon as all that talk about technical issues ebbs down (if it ever does). In the end, it looks like one of these baits where things didn't quite hold up to the hype, like quite a few things in this game.
Judy - lesbian
Panam - straight
River - straight
Kerry - gay
All pretty barebones, mostly a checkmark thing for features to hype in an RPG.
