Okay, can someone please explain to me what the difference between all the mods are? Because I'm kind of stupid, and I'm thoroughly confused. Which is up to date with the current version? Halp please.
Basically:
Expanded Mod: Gives the girls more clothing options and allows some of the girls to get a tan by sun bathing with them at the pool. But, the cast is limited to Rogue, Kitty, Emma and Laura. Mystique was in previous versions of the mod, but she hasn't been full re-implemented with the latest version, and development on the mod has stalled for a while. So, to get Mystique, you'll have to ask around for older versions.
Multi-Mod: I never used it, but it tells you which dialogue options will affect each girl's stats and lets you rename save files for those like myself who play with multiple versions of the game.
Prime Mod: Aka the "Vanilla+" mod where your interactions with the girls are slightly altered/enhanced, such as increasing the stat gains with certain dialogue options so that you're able to have certain interactions with the girls sooner rather than later; such as being able to make out with Kitty when you first meet her. Each girl can gain a special ability, so feel free to read the descriptions on what those do. You get a larger daily allowance which cuts down on the grinding. And this is also where you get your Android version of the game in both modded and vanilla states.
It is highly recommended that you install Prime.
Chonky Mod: ...I honestly forgot what this stated as since I didn't start following mods other than Expanded until this year. But, this is more of less abandoned in favor of Project Redacted.
Project Redacted: From what I can tell, it's a redesign of the characters to have a digital painted look as opposed to vanilla's vectored/Adobe Illustrator looks, and it's attempting to have some kind of story as opposed to just being the sex and harem simulator that vanilla is. So, this is kind of a "wait and see how this develops" type of thing for the time being.
