Well, I also do not see a problem with the first one.ouch2020 I pretty much agree with everything you've said. In my head (not legally, of course) there is a difference between, "Let's have some drinks...hey, she seems kind of amorous, maybe we should see where this goes" and "If I can just talk this girl into drinking more, I'll bet I can do whatever I want to her." In a game, as you say, anything goes--in real life I have a problem with the second but not the first.
If I am having a drink and I get in a conversation with someone, especially a lady, who does not have one, I actually consider politeness from my side to offer her a drink, if she accepts it.
If then ends up that we like each other more than just having a nice conversation ;-), I will see how I feel about it (effectively, interest for the physical goes only so far, but if you add up something more, that is definitively more interesting and worth more effort, but it is a matter of taste).
Had that as well, and in situations where neither was drank, even if we had a couple of drinks.
But I also saw other type of situations and in some case their aftermath - and there were real, not computer games.
