Only a fool would think that Half-Life 3 will be a VR exclusive, but that doesn’t mean that some sort of tie-in with VR is impossible.
I’ll be honest and say that I haven’t followed much about Valve’s involvement with the HTC Vive but that’s mostly due to the fact I know I won’t be able to afford to buy it. If, like me, you don’t know much but want to learn more check out the Steam page.
The question is whether Valve will promote both Vive and HL3 at the same time.
Most potential HL3 players won’t be able to afford the $900 for one but some will but will need convincing and Half-Life 3 could just be the game that convinces them.
I obviously have NO idea what Valve will do but just for the sack of argument, imagine Valve said that you could purchase Half-Life 3 WITH a Vive 1 month before standard Steam release as a bundle.
Would that be enough to convince you to spend the money?
Remember, I am just talking out of my hat here and have NO knowledge of what Valve plan to do.
