FOSS games are good and fun, but to deliver a AAA game with a near-realistic 3D Graphics and a good several hour-lasting story, you kinda need some funding.

Binaries are not in /usr/bin or /bin except for /bin/sh and /usr/bin/env. Programs should not assume fixed paths for binaries and instead look for them in $PATH.
learn how to make a basic website in some flexible programming language like go, rust or python (django)
make a list of functionality of your original website you want to provide an alternative frontend for (as a start, you can expand later)
find a way to retrieve all important data for the most important functionality reliably
implement it into your website
make it fancy, expand functionality, use the same webpaths for you website like as the original (so it can easily be redirected with libredirect or similar)
yeah discord sucks
