Over half a million dollars isn’t “very small” for this type of charity in my opinion.
Not to mention, they seem to admit they’ve known about the issue for a while, but have continued to fund raise and present the charity as if it’s been running along doing good this whole time, but they’ve just been hoarding the money so far.
I don’t see where it’s trying to make it sound controversial. Switching game engines isn’t a “normal” thing developers usually do very often, especially after releasing such high-profile games with an in-house engine.
And with how often you see gamers demand developers “just use a different engine” to solve some specific complaint I think it’s reasonable to remind people why that isn’t usually a good idea.
The only thing the charity has done with the money donated has been to pay for it’s own expenses. The rest has just been sitting in an account somewhere. No grants or anything have been made with the money so far.
It’s tuned for a specific hardware platform right now. Choosing specific hardware platforms for support is just an extensions of that.
However the “PC” platform is basically an amalgamation of any possible hardware combination that currently exists, and is a whole different target for a project like this.
