I feel the opposite. RE3 was held back by cut content and by being too linear. The original gave you options at every step of the way, and the remake went the opposite direction. The opening area (which the demo used) was misleading, because it's the most open the game is. Outside of Carlos in the hospital, everything else is a straight line that ignores everything that made the original so good.
They didn't include Mercenaries, they didn't release DLC to expand or fix anything, and their difficulty modes with all the changes stopped changing anything past a certain point. The game screams "unfinished" at so many points, which is a damn shame because it could and should have been better than 2. Nemesis alone is a giant red flag, they turned him into Birkin's phases from 2 and even copy pasted a boss fight. Mr X's use in 2R made it a better 3 than 3R was. You can see they tried to be somewhat creative with the unlockables, but it wasn't enough. And that's representative of the whole game: there's good, fun stuff in there, but it isn't what the game needed.
I enjoyed it, but it should have been so much more. I'd have happily waited a year or two.
