First off, I'd like to say that I will *gladly update my review* if this game comes to fruition, however, after reading other reviews and experiencing this game myself before and after the last update, I'm extremely doubtful.
Going for a Q1 2015 release? We'll, we're in Q1, meaning the devs have less than 3 months to move this game into a release ready state.
What is missing? Umm, everything?
This game is in a state of "hey I put something together for you to *look* at" - this is not, imo, playable in it's current state.
Sure, you can "play" but there are no MMO elements. No player to player transactions, I've yet to even see another player outside of a multiplayer mission.
Right now, things are extremely clunky, extremely unfinished / unimplemented, and unless there's just massive updates that the devs have ALREADY DONE and have not released, there's just no way in hell this game is going to be ready for a Q1 2015 launch. Based on the commentary from the devs, it seems like we're pretty much getting things as they get completed, which means in reality, for this game to be ready for a launch in a state of actually being finished and a true 1.0 version, I'd say you're looking more at like, 2017, based on the frequency of updates and the fact that the game's already a year behind.
I'm a big time fan of SR, and was really excited about this game after SR Returns and Dragonfall.
The distinction needs to be made that this is not being made by the devs of the two games referenced above. Cliffhanger Productions has chosen their name appropriately, because right now they are hanging on a cliff, and I'm not sure how much longer their grip will last.
