I think you are overestimating your demographic relevance. There are many players, particularly when it comes to AVNs, who do download the PC version and run it with JoiPlay, or just use their PC. I have a mid-range phone and run this without any issues, both the compressed and regular version. Also, if you really think 3GB is a lot, you're falling behind the times.
And no, your phone is not "decent enough to run any game" otherwise you'd not be here complaining. Most mobile games are made low-spec enough to run on any potato device, and that works because most aren't meant to be pretty in the first place, only addictive. Others are limited to literal slideshows with some animation where it is most important. Your phone has only been keeping up because everyone else has slowed down for you.
Again, your phone is not "decent enough to run any game", even if it's otherwise powerful. Most phones are optimized for communication and utility, and not made for gaming. Some have all their power in the CPU and neglect the GPU, while others are skimping on RAM, and yet others have abysmal I/O speeds on their storage. You have to do your research to get a phone that actually "runs any game", and you clearly didn't.
You're not a heroic defender of the "vast majority", you're that guy with a potato trying to downgrade the game for everyone because you couldn't be bothered to get a phone with an actual GPU. Do your research next time.
