I dunno about that, I tried this after finishing other swinging games like ALWL, NIF, Happy Marriage, and this is one of the most singular themed games among all of them, specifically it's for the interracial humilation-themed cuckold crowd.
Not that that's neccesarily bad - it may excel at this, but dont kid yourself, there really isn't much diversity here, despite what the descriptions may read.
After playing once I went back through walkthrough to see if it was even possible to get ANY kind of sharing content sans darrell, and you cant - not like there IS much content sans darrell, unless you count the matt bathroom quickie, oldman fondling or carls 1 scene - but no, if you refuse to humor darrell at start, it's locked into the vanilla path. This is especially frustrating for people like me who like swinging/sharing/cuck games but loathe interracial.
And thats fine, again, game just isnt for my style - but you cant honestly say it's some massive branching "buffet". Despite the anfractuous walkthrough, ultimately, it's "wife is having sex with the arrogant black guy", are you a) enjoying it, b) not liking it, c) not present. That's it.
