I read an interesting post from the creator of the (fantastic) beacon app regarding Ark 2. If he is right, and the customization level of Ark 2 will be much lower (including no mods), it will be very disappointing. Here's what he wrote:
"I am concerned that Ark 2 will not offer the level of customization that Ark has seen. The number of options Wildcard gives us for Ark is incredible and the game is still successful because of those options. Without the flexibility given to us, I don't believe Ark would still be driving the player counts that it does after six years. But these options are a nightmare for Wildcard. They are a pain for developers who have to worry about how every one of them affects new systems. They are a pain for customer support agents, who have to play twenty questions with every admin just to figure out what's going on. And they are a pain for the bean counters because admins take the new DLC content and transplant it into older/free maps. It would not surprise me in the slightest for Ark 2 to be far more "locked down" than Ark. Given the Microsoft exclusivity, I'd even be surprised if Steam mods were allowed. My expectation is that Ark 2 will launch on PC exclusive to the Windows Store, meaning we'd all be playing the Xbox version. Steam support may come in the future, alongside the PS4 support, but I expect it'd still be the same Xbox version, just sold through Steam. I hope I'm wrong. I hope Ark 2 will give Beacon 2 a reason to exist. But what we've seen so far suggests Ark 2 will be a very different game."
