I think I'm right near the end, and I'm having a TOTAL ******* BLAST!!!
The first half was decent, but it picks up nicely. It's a total mindbender toward the end. Yeah, it is short.. I'm about 6.5 hours in, but it feels well paced. I dont like the dialogue, but it seems to be getting less cheesy near the end game. I'm REALLY enjoying this!
Yeah, I can confirm, the graphics are much better than Quake 4, some of the environments are just stunning. And theres one hell of a wicked boss fight, but I wont spoil it!
