I REALLY enjoy Human Cargo. Specially Zed and the Captain paths. It has the right amount of sentiment and kinkiness that suits my tastes haha. I also enjoy Lagoon Lounge and am currently following Tavern of Spear.
You haven't played many yet, I assume.
I played an earlier version of Human Cargo and quite liked it. Funny, I played these routes aswell.
Lagoon Lounge is already on my long list, as is Tavern of Spear. There are older games like Nekojishi I want to play first.
