You're right, I think they would be fun.

Part of the appeal was definitely the retro look, but this is a very-specific retro look that the author worked hard to put into 3D space.

If people tried to make a "retro" to VR games, you'd mostly just get lots of blocky, cheap-looking graphics. But this could really be weird, in a good way.

The modding community did look at it but the first problem was that it's a Unity game built for D3D9 game, which doesn't allow the VR plugin to be dropped in. They did request the developers create a D3D10/11 build to allow that but I'm not sure it ever happened.

Even if it did, VR relies on getting consistent images for each eye for the stereo view, which might be difficult with this style of rendering. It'd be hard to know if it works without trying it!

I don't know, I start feeling off when just watching a video of the game (a little queasy, a bit of a headache). I think that playing it in VR would be a horrible experience.
