I finally put some time into this game over the weekend. It's good, not great. I'm not terribly fond of the Ooze enemies. They just flail around, making the combat more about spamming and less about planning head/knee shots and melee attacks. I know you can shoot them in the head and arm to trigger a stun for a melee attack but in the first few hours, it so hard to do with the weak weapons that I just end up unloading on those mofos. It's different, not better. One of my fondest memories of Resident Evil 4 was shooting a thrown ax out of the air for the first time. Resident Evil 5 was more of the same. Revelations just takes it out entirely. That said, combat just isn't as fun in this game. If the action was reeled back in favor horror, it hasn't worked especially well. Nothing has really gotten my heart pounding. At least, thus far. I'm about 4-5 hours in.
The graphics are stunning. I can't believe how powerful the 3DS is. There are some hiccups with the frame rate but not normally in the thick of the action. The first boss fight had its moments where the frame rate went bonkers and there are a few "loading" rooms where it drops to like a few frames per second but you don't do anything in there except wait for the next door to open. For comparison's sake, it's quite a bit more intrusive than Metroid Prime's loading doors.
I'm not a fan of the customization options as I prefer straight upgrades like RE4 and RE5. I also don't like scanning. Seems out of place and it really slows down the game. Dodging is a nice addition but I'm having trouble doing it consistently. I haven't been able to dodge boss attacks so I'm not sure if it just can't be done or if I'm just being noob.
So far, Revelations doesn't break any new ground with the series and in many ways, it takes steps back. I would have preferred more enemy variety and locales. Also, I would have liked to play the game on a tv but I feel like I'd be less impressed by it. Judging by the trailer of RE6, that's the RE game I've been waiting for.
