Okay, let me put it like this then: Games that have an update will always get more traffic on these forums than games that haven't updated in a while. Threads between updates can be a dead zone. But if once a month a new side game drops, the thread will pick up and end up on the front page, giving it more exposure. Those are the ones that new players check out (no one is going fifteen pages deep to find something). So, once a month, this thread will be hot and attract new people.
Yeah that uses the maxim that more exposure is always good, no matter the kind of exposure you always hit some newbies and in some markets like for celebrity fameor recognizing a brand on the shelves in the supermarket making people more likely to take it off that works most of the time, not in all though. Sometimes bad or questionable exposure (like fast, monthly but unsatisfying updates to stay with your example might cost you more as you gain from it) that does not meet your long term goals with your brand is bad exposure and does not help your brand name or long time profitability.
Like I said it is complex and results are for sure not always as predictable as everyone claims (especially without some serious market research into existing and potential clients and what it would take for those potentials to become loyal customers while also knowing how those changes needed will impact existing clients, which I do not think any game on this site makes enough for) they know them to be based on what they want and prefer

and the risk in the end lies with the dev, not the ones furiously debating, so it is also his right and decision to make in the end based on his best estimations and goals.
If it was that easy quite a few of the gems on this site that do appeal to their potential markets would all be great hits with tons of supporters if they just listened to the vocal criers. I rarely saw a game turn to be way more successful after doing that though, nor businesses

and all add campaigns would be wildly successful if it was that easy and predictable and not bomb at least once in a while and those guys are professionals at it and even they get it wrong at least some of the time.
