I should honestly try the 3rd one. These days I don’t really play FPSs other than replaying HL1/HL2 (and their expansions) and Max Payne 1/2 usually in back to back sessions.
I would of course play HL3 (still have to play HLA; I don’t have an index).
Would love to try both. I wouldn’t even mind Hl1 in VR (HL1 is my favourite in the series, other release are examplry as well).
