I'll wait for reviews and player feedback, for several reasons.
-Gameplay isn't a genre I'm familiar with. No way of knowing if the fundamental dynamic will be compulsive entertainment for me, which with an FPS, RPG or strategy title is generally not an issue.
-Not coming from a tried-and-tested developer. I've massively enjoyed some of Creative Assembly's older strategy titles, and have been disappointed by some of their more recent ones, but these are moot points as the vast majority of the team are new to the company (and it's an entirely different genre).
-Multiplatform release, which has come to be synomymous with "compromises for PC users". Don't particularly fancy playing an unstable build with negligible post-release support, slow and clunky controls/camera/interface, poor mouse+keyboard functionality, threadbare customisation and inconsistent graphics. Lack of modding capability has become the norm, sadly, so won't affect my decision.
-Burnt by a number of disappointing pre-releases and Alien franchise games in the last few years. Part of it, admittedly, is that I'm not finding many games today that really cater to what I enjoy.
