The ones ive played aren't necessarily more fleshed out per say but they are still full games that aren't dating Sims or puzzle games or mods. They are:
Breeders of the Nephelym (3D, breeding game. All porn. Basic mechanics, Still being developed)
Wildlife (3D, amazing animations. Mostly sandbox and scene creation right now but with plans for a full quest line and such)
Carnal Instinct (3D, good animations. Rpg style game with quests. Still in development.)
Hunt and Snare (3D, rpg-ish style game about managing a ship and a crew and "hunting". "Hunting" is shooting roaming characters with a tranquilizer to capture then for your crew. All characters are furries. Still in development)
If you don't mind pixel graphics and RPGMaker games then I would also check out Princess and Conquest. I had a good bit of fun with it.
A little late to the post but I'm an apprentice electrician. Inside wireman so mostly commercial, office, and industrial buildings.
