Well nice April joke Wildcard ! ( But there is still few days before April ... )
Ark in mobile will be a big fail. PC's optimization is not good for the moment.
Just have a Look on how it's running on computer ! 6FPS in some area with 16GB ram and GTX1060...
With a phone hardware, you will have a fixed picture, not a playable game.. or a piece of crap that is not shown in the video. ( a phone showing a promotional recorded video of PC experience ).
At least maybe they will not have 5GB update to download...
Wait and see
