Smirniy v2 is completed and has an ending, but it uses the original DarkSilver game as its basis, it's pretty much a bunch of mods on top of the original game, so it is incredibly grindy. Honestly, just use cheats on your stats, its better than spending about a month of in game time just grinding stats so Max can do anything. The quality is a bit inconsistent, but its a perfectly playable version of the game.
Remake Story is also based on DarkSilver's original, being ported into Ren'Py with new content added specifically on the NTR route. However, it's abandoned, and not actually finished. And if you don't like NTR, then there's not really anything new for you on that game.
Another Story Rebuild is still in active development, with a more structured story imo, with some new concepts and stuff like Mia the lawyer and what not. However, development is slow, and the older Another Story technically has more content. In terms of grind and stuff, Rebuild is the best version imo.
