It's pretty safe to say that many of us choose video games as a means to relax, to escape the daily grind and instead dive headfirst into fantastical worlds, where we're not just Bill from marketing and instead, we're Gramblor The Alcoholic Dwarven Warrior on a quest to smite the demon that slew his family and kicked his dog, and for the most part, video game developers will stick to some common tropes in order to fulfil this power fantasy.
Such tropes include a heavy focus on providing a gentle but rising difficulty curve, as if the immersion is broken by a game being too difficult then the player might never return to complete it, which is basically the death knell for any video game's chances of success.
Yet there are some titles out there that absolutely wipe their arse with this idea, and will either bludgeon the player with brutal difficulty from the start, or have rules so complex that you need a masters degree to even get through the tutorial. And these entries are just such titles.
If you're not already familiar with these games, then take my advice, steer clear as they will eat you alive and then mock your dead body. Cheers.
