Gonna take the plunge; reviews seem to report that it's still very much STALKER underneath the bugs. This is exactly what I hoped for, I think this might go the way of Cyberpunk 2077 when all is said and done, and be patched into a hit. It's brutal and nasty, and the open world creates some insane organic scenarios.
Edit; 20-minute download including the day one patch isn't too bad.
