Alright, I'm usually behind Wildcard and supporting them and defending them countless times, but this-- I cannot defend or support them, this is just wrong.
1) You knew Jesse and Jeremy were overseas, it's obvious things would be delayed/not finished. Not telling us this via your own forums or even social media beforehand, then telling us the day it should drop is inexcusable.
2) Not only are your Xbox fans disappointed in you, some of your PC fans are too.
3) Xbox has continuously missed out on events since release, this isn't new, but promising us we'd finally get an event and not delivering at all and basically telling us "Wait until December for the next event" is arrogant.
Basically what I'm saying is, the community is sick of your excuses and the lack of communication. Either you guys need to buckle down and get serious with this and treat your community the way they've been demanding for a long time now, or you'll just lose fans and players. That's not good, I mean yeah, a lot of games/companies lose fans daily, but those are BIG companies and games like Call of Duty and Destiny and they gain more players than they lose. That's not the case here, if Ark continues down this path only your 'loyal' players will remain after the dust settles, and that loyal bunch isn't going to be enough to support the game, I'm just being honest here.
Do something to make up for this inexcusable screw-up. An Evolution Event isn't enough to make up for this. Best option is to finish it anyway and release it sometime in November. Nobody will care that it won't be on time for Halloween, we just want the event.
