Have to say, this game is tougher then my memory serves me. My girlfriend is catching me screaming odd lines like "keep ducking and killing me asshole!" from the other room.
Played the GC and PS2 versions religiously. Tried the entire PC + texture pack vs. Dolphin mess and got fed up with the work. So it's been awhile since I did a full play-through.
Game looks pretty good with the HD upgrade. Less stand-out gaudy textures then the packs for previous PC version but a lot of low res hurts the visual experience. Mouse controls are OK but I hate the QTE. The mouse shake doesn't register well. QTE's are garbage regardless. I also find that Leon "spazzes out" with the mouse controls too often. There is a trick to having the mouse focused on a specific field while doing quick-turns and navigating KB + mouse. I haven't found the trick yet though and end up staring at room corners, enjoying the paint work.
I had an early chainsaw death and then saw better drops... So I assume the game dumbs down when you perish. I'm not sure I realized this years ago unless I'm imagining things. Regardless, I'm now not continuing, not to drop my death count, but to stop difficulty assisting. Too lazy to research the truth.
Parts still suck. Boat controls and escort missions come to mind. Took me a bit to figure out that the turn part you do with Del Lago is a dodge and fire, not a free shot. So you have to give the boat a little turn. Led to some frustration. Then I took him out with no damage once that puzzle was solved. Ashley is OK if you just have her hold position way way back. Pretty pointless though. Oh and Luis, house scene. Can you not jam into corners and constantly duck, not assisting in any way, cause you are jamming my line of sight? Thx buddy, I'm not invincible like you.
El Gigante round 2 with 80% health, one body slam, I'm dead... Shesh. Ended up taking him out with a Red 9 and no damage though, which was rewarding. Chainsaw fanatics who take a truck load and one smacks you. The merch when he sees you have too many herbs and won't part with the spray. The head craps which spawn sometimes with a shot lower then a head shot. Doesn't seem right.
All that said and less then 4hrs in again, this game is a fucking MASTERPIECE. I don't even know why I would go next-gen or upgrade my GPU when I have RE4. 3rd on the all-time list for me.
EDIT:
Looks like I'm right and there is sliding difficulty. No thanks Capcom. Give me death or give me victory.
