Yeah, this seems fake to me. A map that size would be stupidly big for a game with a 12 hour main story, unless they fill it with loads of repetitive side content. They think they can win GOTY 2019 with a game like that?
Batman Arkham games don't have repetitive side content, so why would they do it with this game in particular? Curiously have you not played them?
I was expecting it may be as of now as well, but even then I question how great of a game they can make in that time frame with goals as ambitious as are currently speculated.
I know that it says 3 hours of story for each side quest. The reason I said it would be barren is because side-quests which are as long as 3 hours require a lot of time to make, especially if they use that length appropriately and don't pad it out. I don't think they would be able to make a lot of side-quests under those conditions, even in the span of three years and with a large staff. With an open world that's 1.7 times bigger than GTAV's, that means that a lot of space is either A ) going to waste or B ) isn't being used to contain unique quests, but rather as a detour in the middle of said quest. I don't think either scenario is very charitable.
If "over 2 years" is closer to 2 1/2 - 3 years, then I admit that my concerns might be a bit overblown. It's just speculation anyways .
Arkham Knight has modern assets which they could use for the game. It would save tons of time and Arkham Knight is still among the best looking PS4 games so it shouldn't even be a problem.
After what happened with the last Batman game on PC, nah, I'm good. Besides, WB is greedy enough that they will definitely consider making it exclusive to Epic's store, so sod that entirely.
Have fun missing out on amazing games because of platform bias. Also, its not like you pay any more for games on the Epic Store.
