Kept hearing about AW but had yet to check out gameplay - looks very fun. HL:A is rated highly online, said to ruin most other VR games for some due to how amazing it is - whether they are being hyperbolic, who knows. High hopes for Eleven Table Tennis. With a slipped disc, can't do anything too strenuous unfortunately
PS VR is cool tech. Would appreciate if Xbox brought VR to their consoles, but seeing as Microsoft recently discontinued their mixed reality headsets, not holding my breath...
Little knowledge on Steam VR outside of cursory glances at Steam Link discussions. PCVR seems to be the clear next step for the budding VR enthusiast. Outside of games and virtual environments, viewing 3D scans of cars would be great. A standalone headset geared more toward media consumption with light gaming on the side would have much utility - an AVP without the walled garden experience and exorbitant price tag.
Upgrading the stock strap/acquiring an external battery are usually recommended to newcomers; the seemingly affordable price of the Quest can quickly multiply if you opt for PCVR and upgrades.
