I think my thoughts on this have changed over the years... It used to annoy the fuck out of me to see every MC with a 12-96 inch cock. Like... some were longer than the fucking girls torso. The fact that all MCs had a cock bigger than the girls thigh was just a joke.
Then... in the last year or so, Ive run into a TON of games where the dude has a little sausage. And I'm not even talking about cuck games. I'm talking about normal games, and the dev is all "Oh, yes, put your huge cock in me!" in the dialog. I'm sitting there mentally measuring this 3-5 inch peter against other items in the scene to make sure I am not seeing something wrong. Then, a few times, I see a 6-7 inch, which if I remember correctly would be considered average. Even that feels wrong now. My first thought here is "Fuck, was this a cuck game that didn't have a tag?" But no... Seems some devs either have never seen a non Japanese cock before (sorry, couldn't resist), or are fighting the footlong third leg meta. And for some reason, this feels worse than the absurd and immersion breaking horsecocks.
I can't tell if it is because I was so inundated with massive dicks in porn games that it became the new norm, or if I just associate small dicks in porn games with pussy ass cucks and that makes me hate it.
For devs: If you don't have the tools to help you figure this out (your own non-tiny-cock, the internet (eg, google "dicks"), etc), and you want to make a "huge cock!" here are some rules of thumb:
1: First, it better fucking be bigger than his thumb. Fucking seriously dude. If you do this and are not trolling and call it a huge cock, please find a new career/hobby.
2: If a female's (who is not some fantasy world giant) hand can completely hide the entire cock or even the shaft with just the head sticking out... its not huge.
3: If you can put it in a girls mouth to the root and zoom into her head and see it it not even near touching her throat... yeah, that's not big. Not even average.
4: Most small hands are about 3inches across (not counting thumb) or less (I have small hands for a dude, but large-ish compared to most girls and mine is about 3.2in wide). So for a 6in dick (which is not "huge"), it should take 2 fists from the root to completely cover it AT LEAST. The smaller the girl, most likely the less it would cover. If you are going to call it huge, I feel it should be AT LEAST 7 inch, but prob 9 to be safe. This means about 3 "small man hands" or almost 4 "really small girl hands" long.
If you just don't want to put huge dicks in your game? Fine. But dont make every female in the came call his little Vienna sausage "huge". We have all played other porn game where the "huge" dick is bigger than his fucking entire leg. You are just making them laugh. And not with you... at you.
