So you'll find quite a few meaningful upgrades in the remaster (this makes it worth checking out even if you played the original). The switch to unreal engine 5 brings some really nice visual improvements, and they've added a sprint mechanic that changes how you'll move through the world. What's particularly interesting is how they've included major expansions like shivering isles and knights of the nine right from the start, because these add substantial content to explore.

The stamina and stealth systems have been reworked to feel more modern (you'll notice this especially during combat), and the improved lighting makes sneaking feel more impactful. Something worth keeping in mind is that while most dlc comes bundled in, the classic horse armor is still a separate purchase - kind of amusing given its history as one of gaming's first controversial microtransactions.

They've also expanded the voice acting for different races, which adds more personality to the world (this helps make each playthrough feel more distinct depending on your character choice). If you're planning to dive in, keep an eye on future updates since they're actively working with community feedback to refine things like the sprint mechanics.
