Done already? That feels a lot shorter than the character storyline in part 1, no?
Paradise Lust 1 was 3 years in development (from starting to public 'full' release, not counting the 4 additional bonus updates); Paradise Lust 2 aims at 2 years, with public release sometime around spring 2025, after which point that team will start on a new project, hopefully Paradise Lust 3. In addition we'll probably do the same kind of bonus updates for another year (so 4 new scenes for Summer/Autumn/Winter/Spring sales).
3 years was honestly too long; it meant we couldn't fully fix game design issues that we knew about, because the game's structure was already set. The obvious pain in the ass (literally, in Karen's case), was the decision that each girl would have 4 'love' tiers, each with a sex scene associated with it. It meant that the girls introduced late in the game (like Grace and Rachel) had their events feel 'rushed', and some characters (*cough* Karen) got more TLC than she really needed. It also meant that some repeating minigames (fishing, bartending) overstayed their welcome, because they were needed to generate Sex$.
Paradise Lust 2 let us change some of the mechanics, remove all the grind people hated, reset the resort and set up another storyline.
Edit: I said 4 years, but that was Love of Magic (Dec 2019-Sept 2023). Paradise Lust 1 was 3 years (June 2020-May 2023), while Paradise Lust is aimed at 2 years (June 2023-April or May 2025).
