Red Dead Redemption 2 is a phenomenal game, but much like it's predecessor, it's yet to see a release on PC. The original Red Dead Redemption never did see a PC release, mainly due to technical issues that made a port difficult to create, but in yet more good news, it seems Take-Two are more optimistic about it's sequel.
Take-Two's executive, Strauss Zelnick, spoke out today stating that he does not believe there would be any downside to the game being released on PC, although he stopped short of confirming plans to actually do so.
He made the statement during an investor briefing, in response to one comment from an investor who stated he felt that a PC release would be a "layup".
There is no downside to releasing the game on PC.
So it's still not an official announcement, but the evidence is mounting. The official companion app for the game had references to a PC version alongside other platforms in it's source code, as well as former programmers listing PC as a platform on their CV's in LinkedIn.
Hopefully a PC release will be announced at E3, but stay tuned to GameFront for more as we learn it.
