I spent way too much time on most of the Kegani Laboratory games and more time than I should have on Nebel Geisterjaeger. I like the grind to the prizes in those games
Probably eturnum the story and setting is just awesome. I play the game more for the story ans difforent virtual setting more than the sex. We got horror, mystery, cowboy, si fi, Romans and many more settings
Probably something like Four Elements Trainer. But the game that felt the longest definitely My New Family, since I actually felt like it had a well-written story
Sims 4 but modded out the wazoo lol jk. Probably big bang empire when that was still active. My account was lv 534 with out spending a dime. Me and my uncle used to be in the same clan. probably the only dudes in the clan lol
overwhored,blacksoul 1 and 2, a new game, the mercenary's adventure.
and replaying it star knightess aura, Alansya Chronicles - Fleeting Iris, Hentai High School+.
I can easily say summertime saga and pandoras forest, summertime because they have a ton of mods for it to change it up as well as they have had tons of content in it. the second because I led a thread about it for translating it and had to test and find all the easter eggs which that game had a ton of.
