It's like a original Resident Evil with a few extra things like 1st person knife battle, where you can get a certain rewards if you win, which is very interesting addition, but can sometimes get really annoying, well it does me. The other things are those puzzle boxes located in saverooms, where you can get more items, like a Red Herb for example, other minor change is when you beat the Plant 42, and later when you come back, in the same room where you killed the Plant 42, you will go head to head with the Yawn the giant snake in 1st person knife battle. This is one of the hardest fights in the game. There are also few more changes, like some different enemies can be found two at once, like a crow and zombie. And adding Chimera in the Mansion Library was pretty neat. There are more of these changer, but if you don't like them, there's a Original classic style to play.
