It's a bit hard to make generalizations about the remakes, since all three have very different approaches:
- KQ1 got a 1:1 remake. The gameplay, text, and screen layouts are the same as the SCI version. The exception to this is that they added an optional no-dead-ends mode.
- KQ2 was made into essentially an entirely new game, using the original as inspiration and as a framework. It still has mostly the same characters and inventory items, but their significance in the story is generally very different.
- KQ3 took an intermediate approach. It's still basically the same story as the original (with only tweaks to make it compatible with the changes made to KQ2), but they took the liberty to change or improve some of the puzzles.
There are things in KQ2 that were very straightforward in the original but much more involved in the remake. For example, in the original you would just find Neptune's trident on the beach, while the remake introduced a whole quest for retrieving it. So I can't categorically say that they're more forgiving.
I will say, however, that the general
trend absolutely is towards being more approachable. The removal of dead ends is a huge improvement. And the remake of KQ3 in particular has a lot little quality of life improvements. The games do still feature a lot of deaths, though, and no auto-save feature, so it's still advisable to save early and often.
