It should definitely be a toggle. I know that without sprint, with the current size of the maps, some jumps that you could make with sprint+thruster aren't do-able without sprint, but an increased movement speed would compensate for it.
Before the first gameplay vid of H5 I hoped they would go the route of making "Arena" a non sprint game mode. Sprint would be limited to larger game modes (where it has the most use). This way you'd be able to have the best of both worlds, and as a toggle, people could forge smaller maps with sprint in mind if they really want to.
So I really hope sprint can be toggled. I love sprinting but I think there should be as many options as possible.
Whynotboth? I enjoy having collectibles to find and encouragement to try and figure out ways out of the maps or little nooks I might miss otherwise. But from the standpoint of gameplay, having them unlocked from the get-go gives players more flexibility.
Also, I really hope they continue the CEA/H2A trend of having nonscoring-type skulls that aren't just ratcheting up the difficulty. I'd love a "pacifist" skull that just prevents enemies from firing on you and/or spawning so you could just roam the levels in peace.
And dammit, we still need the "weapons replaced by mouth sounds" skull. It would be too good not to have in a game
I guess it depends on how you go about having both.
I suppose they could try having the original H3 skulls unlocked from the get go (except for stuff like IWHBYD or Birthday Party) and then make all the fun party skulls stuff you need to find. That's be pretty cool and give you incentive to find the rest.
This goes back to a debate I had a while back about the point of finding stuff in games. It irritated me that 343 made the terminals something you have to exit the game to view. You need to exit to another app to view it in the first place and at that point you might as well just watch it on YouTube. So it completely negates the point of having the terminals in the first place.
The fun in bonus stuff like this is the effort in finding it (or at the very least getting it). I mean if you want to go watch it on YouTube then whatevs, but that shouldn't be the default of the game.
