I dove deep into the adulty parts of the interwebz and looked around a bit.
Well, there is a lot of Renpy in that list, so expect those games to be a similar experience to Treasure of Nadia (so not really worth your time).
Leap of Love changes the formula to at least to such extend that you are boosting your skills to impress a girl and live happily ever after - so the adult part isn't the main focus as in those other games, that are just an excuse to throw mediocre renders at you. Honestly, reading up on Leap of Love, I like the concept that you are a frog turned prince, but now you have to make sure a princes will actually want you around for ever after, so you don't get re-frogged. Adult version of Long Live The Queen, without being the queen.
HuniePop is the only one on the list I actually played years and years ago. It is a decent match 3 game, and I play match 3 games to zone out. But there is so many, I have enough SFW choices that I don't need the NSFW ones.
Sapphire Safari seems to be national geographics meets monster girl porn. So again at least it gets points for trying something different. Personally not my thing once more. But then again, nothing in that bundle is
If I were to play any of the games on that list, it would be HuniePop for matching threes, Leap of Love for helping an amphibian out, or Sapphire Safari as a walking simulator. But match 3s and walking simulators you have better choices in the SFW part of gaming, because as always, those aspects of a game you aren't interested in do affect the ones you are - dev time is limited. For example the devs who thought King Arthur Knight's Tale needs a VS mode, took time away from the programmers that could have been used to properly integrate the free dlc into the campaign.
Which means, meh. I wouldn't waste my time if I were you.
