Umm, no.
I will continue to follow the forums and hope for the best, but untill UBI removes the invasive DRM and fixes the innumerable bugs that have been present since SH3 - inability to dive past 180m without running at flank speed, for instance - I will vote with my wallet.
I refuse to pay for a bug-ridden, half finished, and sloppily scripted mess.
Doing so would only reinforce to UBI that this is an acceptable business practice. I can only vote for myself, but vote I shall, and I refuse to be moved, coerced, or guilted into supporting SH5 based on what it "may become".
I'll buy it if, and when, it meets MY standards as a consumer - not yours.
