I remember pondering about bad video games in the past.
The best way to begin, is to take a series : like Baldur's Gate : and release a sequel that is completely unrelated gender-wise. Baldur's Gate : The Boat Racing Simulator.
The game has to have as many complex, unimportant attributes as possible. Because while everyone likes to have some variety in skills (Axe skill, Sword skill and so on) i doubt anyone would enjoy having a "Left hand fork usage" ranked from 1 to 100.
Also gear has to be overcly complicated. Everyone likes to have a choice between m4 and ak47, but what if we add 29 versions of the ak47?
Next we have injuries. Different hit zones are these days a requirement, but what if we went a step further? Who wouldn't want to play an fps with notifications like : "Fractured left index finger, penalty to fork skill"
Let's not forget bugs. Daggerfall and Gothic 3 were simply amazing in this department, and this kind of broken gamestate is what we want!
The graphics engine can not be optimized for any card currently avaliable, and should be recycled (or rather 100% ported) from one of the game prequels, preferably one released over a decade ago.
Lastly, there should be some complications involved with installing as well as uninstalling the game. I remember one of the old games partially formating your hard drive when you removed it.
As a cherry on top : adds, secuROMs, requirement to be connected to the internet, an intrusive, no-privacy EULA..
..and we may have a winner.
You may laugh, but it's only a matter of time before a game will have all of the above combined. My only hope is that i will be dead by then.
