i know deluca family's dev from before his game came out. at the moment we wasnt even sure (and hoped) that his game will reach a hundreds patrons in a month.I'm going to use your question:
Do YOU have actual real stats about this?
Odd as it seems that plenty other sites also load up these games including "The Deluca Family" just do a search for incest games or even the game's title itself gives me 9 sites on the first page including this site and you will see enough sites for all others. don't use Google, use DuckDuckGo will give you more results.
Again we all know why we are here let's not pretend to be saviors of the devs and that we are not DL/STEALING/PIRATING/PLAYING content that we should be PAYING for, that's all I'm saying. If I DL 30 games and only support 1 dev it's still not viable as a Marketing/Exposure tool because it's not generating enough revenue VS the freeloaders like US, me included.
It's called recognizing onerself and not being in denial. We are not here to jugde anyone but need to be realistic.
Having said that I see you are a "Dev" and i would correct that and say you are a hobbyist turned Dev who LOVES doing what you do and SHARE it free because you LOVE what you do and since your product is GOOD people support you for it and your hard work, note it is not meant as an insult but actually a praise to you for your love and passion on what you do as i have read some of your post around the site and you seem like a genuine cool and somewhat funny person.
But not all "Devs" are like this the mayority are making games for PROFIT since they are not a BIG Studio they need the revenue for future projects, but that is economics, investment/production/product/profit but here it works production/product/investment/maybe profit? and that my friend is another subject that has nothing to do with this thread so i'll leave it at that.
i clearly saw how his game growed sinze here. and its not a surprise. my pseudo-stats are more correct than yours if i can say.
like you say, game came out on various website. but keep in mind that in most of time, game came from here, and then are copy-pasted on otehrs website, including the whole description. wich give a statistic more correct.
i can say i am a dev. but not the best. still, i wanted to make my own game and got a way to do it. of course i enjoy doing it. every dev should enjoy what they are doing or overwise, they would turn into some kind of... i dont know.. bored person who dont want to continu what he's doing because fuck that.
funny fact is, that was the feeling i (and maybe others) have got from this dev and game here during development. it seemed slow, took eternity and sometime turned with crazy twist coming out from nowhere or low idea (not bad idea, i mean things that didnt fit well in a game like this, specially about the survival part of it)
but heh. profit is here and if want to keep it, better work on it. ( or fake it like Slonique XD )
