I think total between my Xbox and PC, I've logged about 500-600hrs in that game. It's a guilty pleasure, but I really liked it.
If you still have your copy I'd be willing to boot it up again sometime.
I have it on both Xbox and PC as well. Didn't know/care much about Resident Evil before I got into Two Best Friends Play and tuned into their Resident Evil 2 LP (their first full LP) back in early 2012, recognized the name Racoon City, recognized the name from posters at GameStop and other mentions/advertisements of Operation Raccoon City, rented it from Blockbuster (yeah, they were still around thankfully), liked it, and got the fancy
special edition from GameStop shortly afterwards. Then a month or so I got RE4, and in October I got RE6, then Revelations the next year, and Rev 2 when it came out. To this day they're the only RE games I've completed (oh, and Umbrella Chronicles), but back in 2012 when I got ORC and RE4, I spent
a lot of time reading the wiki, so I know more than I should.
I have almost every achievement in the game, too; missing a couple multiplayer ones and almost all the Echo Six achievements because I still never completed it. For some reason I thought I'd do a blind let's play of the Echo Six campaign and only got two or three missions in.
Then I got the game on PC in late 2015, and that was a fun time. First I bought it right before it went on sale, so I had to get a refund, wait for it to process, and then get the game with the new sale price. Then it wouldn't work because of Games For Windows Live, which I don't mind when it works fine like in Halo 2 Vista, but here it was just straight not letting me play. Had Microsoft support do some black magic to get it to work, and nowadays it seems to work fine. Though the mouse aiming is a little stiff for some reason...
Sure, it's been a while since I've played the games, so I'd like to play. Which platform do you prefer?
