1. Yes.
2. Cheating is hands down the best. At least until the last cheating update, which fell off. Majority think Blackmail is the worst. I agree.
They're all about equally developed content-wise. Just some executed better than others.
As far as "looks interesting", I gave this game 1 star playing the first RPGM chapter. Then gave it another chance downloading the Renpy updates (so skipping to Chapter 5). Impressed with the noted improvements, I redownloaded the RPGM build to play through from the beginning. It gets better. But it's still wildly uneven, with some incredibly stupid dialogue, plot-turns & ridiculous graphics for the male characters. And SO much filler, from characters and side stories no one at all cares about. But when it's good, it's good.
