A simple walkthrough mod would indeed be useful, giving you a clear warning about critical choices that lock you into each route, closing others - but, for all but the earliest routes you can get into (if I recall correctly, Melinda's route should be the first, if not Samuel's) you need a lot of pre-requisites. Moreover, many choices lead to multiple consequences, meaning a complete walkthrough mod would need to add extensive amounts of text to those choices. You can get the same information with the Universal Mod, as it will tell you all the variables that change for each choice. I never dealt with rp but I guess if someone took the universal mod's code as a base, and "translated" those variables to something the player can understand, it would make for a pretty good walkthrough mod.
Having said that, it's exactly the same information you have in the walkthrough -
YedaGames gives you all the variable changes and all the pre-requisites. And following the walkthrough can be tiresome and take some of the fun out of the game, hence why it seems like a sensible option, if one can relinquish some control, to use the walkthrough so you can get into the main and secondary routes that you want, and let your gut freely guide you through the rest of the game. Honestly, the non-love interest routes simply "happen" if you roleplay consistently: be dominant and you end up in the dominant route, cower to Dominique and you end up her slave, resist her and you end up her enemy, etc... Bimbo might be trickier, but the general rule is if you take up every opportunity to get sex, you end up in one of the bimbo routes. Tanya's routes seem simple as well, if she thinks you're a slut she'll offer you to do porn, if she respects you she'll share her secrets.
The real deal would be if someone made a graphic map of the game, that would rock, but would be a daunting task.
