Preordering games is bad for the industry.
Guilty as charged. And yeah, I absolutely agree, it's the gaming equivalent of buying unseen. I'd often do it to get the collectors' edition but was badly burnt by that when I bought Dragon Age Inquisition's CE which was crap: shoddy, broken and falling apart and only bore a passing resemblance to the "concept art" of what we were supposed to expect. Any other industry would be hauled over the coals for misleading advertising.
In hindsight it was probably worth it for the rather nice set of tarot cards which were soon being passed around on Fleabay for more than the cost of the CE itself but it taught me to be more cautious in future.
