The game only has a demo and expecting full release next year iirc. "Robin morning wood" is pretty good, art ehh, but good enough for me. Mixed of human, furry, monster, orcs and demon angel stuff too made by sonpih One game i found was "lust for adventure" it has options for all pairings, and the m/m is pretty good. Being someone who finds what little i can, i did enjoy SoC. I don't know many other games, but a list i can make mostly ends up being visual novels like morenatsu, black lagoon (which is censored), tennis aces (doesn't have the nsfw implemented yet), and a few others. I actually like the m/m stuff in seeds of chaos, but my only complaint is that theres not enough of it. There's never anything resembling an equal amount of content and often you'll be forced to suffer through non-optional _/F content whenever the original dev forgot that some of their players don't care for the concept. This is the same issue I mentioned above about Seeds of Chaos the original devs don't actually like M/M content so they hired someone else to do the tiny amount of content they thought was necessary to appease the group that wanted it. Your ability to enjoy these is heavily based on your tolerance levels for the paired fetish in question. Usually furry or feminization for some reason. The fetish in question is utterly unavoidable. These games have an equation that just substitutes the PC's/partner's correct parts in, and while they are theoretically very inclusive tend to be very boring after awhile due to how samey everything is. Generally, with M/M content in most of the games posted here you're going to run into one of three drawbacks: There are a few jewels, but they're mostly mentioned in the other threads which have been quoted above. In my experience your pickings are pretty slim on these forums. To be frank, it is objectively worse, and I found the very first M/M scene in the game feminized characters when they should be at their absolute most masculine a cardinal sin if ever I saw one.
I found that the art and writing in general in that game are very good, but the M/M content doesn't hold to the same standard. Alright, now to contribute a bit myself personally I can't recommend Seeds of Chaos.
