Get the mods for Half Life 2 + episodes as well. It's almost as advanced as Alyx but with more challenge, which you may want after you get a handle on Alyx (and you get back the crowbar).
If you're a gun enthusiast or just would like to mess around with some of the most detailed weapons VR has to offer, I strongly recommend trying out H3VR (Hotdogs, Horseshoes and Hand Grenades is the full name I believe). Yes, it has never been on sale since it came out, but it's 100% worth the 20 bucks they're asking for. There's also an awesome multi-player mod for it called H3MP, as well as heaps of other content mods.
Skyrim VR is on sale, you NEEEEEEEEEEEEED to mod it to make it playable (it's a dogshit port). I tried pirating it but the mods required to make it a good VR experience only work with a different version
