Just to be precise: ARK is in "Pre-Release" status. This is *NOT* a "pre-Alpha", "Alpha", "Beta"....
In the sofware release versionning system you have:
Alpha (+/-pre-Alpha)
Beta (+/- pre-Beta)
Release Candidates (+/-pre-release, RTM, RTW, ...)
So ARK is in a way much more advanced stage than "pre-alpha".
If it's buggy, yes we can fairly complain about this "PRE-RELEASE" game (that we bought like a "real" game by the way).
And beside perfs issues (on XBox at least) and bugs, the game is GREAT! Keep up the good job guys.
