I hope they push the graphic levels high, REAL high! I want everything to look detailed and have motion blur just like Crysis. I don't want any fake looking Aliens or Colonial Marines, I want everything to look visually top notch. This is Aliens people, it deserves the best from everything.
Most of all, I hope it's a well optimized game for the PC with no bugs or fps problems. Thats a deal breaker right there for me. Nothing is more annoying than a lazy ported game filled with bugs.
