Games that are that cheap before release which are not part of graphics card promotions (ala Arkham Knight), are instant red flags in my book. Add to that fact that it is also is a WB title AND a movie tie in and well.. yeah. In it's defence it is made by the guys (Avalanche Studios) that did the Just Cause series, but they have to be very busy with Just Cause 3 so it makes me wonder who is dealing with the port!
So yes like you I'm put off by the price, although it does "look" good pre-release we all remember Aliens: Colonial Marines right....
These days there are very very few titles I'm willing to pre-order and I'd hope I'm not alone in that mind set.
