That reaction to that Tron Runner that was revealed during The VGAs is really interesting.
Like it's just an endless runner. Nice visuals and animations, but it's still just a behind-the-back endless runner and it's $10 on Steam
If it had been a mobile game that had been ported to PC, you just know people would be shitting on it for being overpriced. But because it's Tron and it's on PC, the reception is positive, even though mechanics-wise, it's like dozens of other endless runners you'd find on mobile
Same with how a mediocre game like Fallout Shelter was praised and well-received in the GAF threads
I tend to find most people dumping on mobile to have had either little first hand or incredibly out of date experience, or are otherwise "low information". So easy to combat almost every argument a mobile game hater has with dozens of counter examples. Even the "no buttons" thing doesn't even really apply any more.
People aren't willing to actually try something until they basically have a good reason to and then, lo and behold, find out it's actually fun. Fallout Shelter was exactly that kind of thing where it took a game based on a major IP, the fact everybody has a smartphone in their pocket, and a NeoGAF OT to get people to try it out. And while good it isn't even great relative to the literally thousands of other better mobile games out there (well, that's a personal opinion obviously), so those haters could have been having fun on mobile a lot earlier.
It's somewhat similar in my opinion to the kneejerk negative reaction to a free to play label. People happily jumped on the Hearthstone bandwagon and quite possibly into free to play for the first time because Warcraft/Blizzard. Suddenly the devs aren't "greedy" and the gameplay isn't too grindy, even though there are literally thousands of other quality F2P games out there balanced exactly the same way. Valve somehow gets a pass too for Team Fortress 2 being "free to play done right", even though their monetization model isn't meaningfully different again from thousands of other F2P games out there.
Basically, people are willing to give something the benefit of the doubt if they are familiar with it (or the people behind it). And skeptical or downright dismissive if they aren't.
