Not a native speaker, so I could be wrong about this:
I’ve seen a construction using proper nouns (eg. Annas Haus) where an “s” indicates possession, but no apostrophe. This doesn’t seem to apply to non-proper nouns (das Haus der Frau) and is different from normal genitive construction that adds an “s” to masc/neut noun genders (das Haus des Mannes)
I didn’t like it because they spent so much time doing character development (Barney in particular) and just dumped it all out the window.
The problem is that “women are attracted to nice guys” implies that “being nice” itself is “enough” to be attractive. Guys get this idea that all they have to bring to the table is “I’m not a jerk” and the ladies will fall into their laps. The problem is, the jerk down the road is in better shape, has interesting hobbies, and/or has a real, dependable job. Being “nice” is like having two slices of bread and saying you have a sandwich. If you don’t put anything between the bread slices, everyone’s going to opt to order the burrito instead because it’s got an actual filling.
If you haven’t played it, Divinity Original Sin 2 is a fantastic Larian-made RPG that uses a non-D&D system.
