I got this game a few days after launch, played the first two chapters, and lost interest- I just didn't know where it was going and I wasn't sure if it was my kind of game (it's my first real Resident Evil title). But I just restarted a couple of days ago and I'm having a blast- just finished up Chapter 5. I'm really enjoying the tightness of the combat, especially in the hallways (and that damn Rachel boss battle...), and I've mastered dodging and reloading on the fly. The story doesn't make a lick of sense to me but I honestly don't care because I'm having such a great time. For me, the tension is very fun and has me checking every corner for a new foe. After the first boss battle I became braced for some gritty combat and I'm now totally engrossed.
I haven't tried Raid Mode yet, but I'm excited to give it a whirl.
