Designing for all systems will just hold the game back. They need to focus making monster hunter as best as can be or else playstation and xbox owners won't be satisfied and they will lose interest
The power gap of switch and og x1 isn't that big. Just remove some textures, put sub 720p resolution, and try to hit 30 fps, etc.
If Doom for ps4/x1/sw is possible, than so is a monster hunter game.
I mean, switch version will most like be miles behind other versions(almost a diferent game), but you will have mh on a handheld, and things will look "ok" on a small screen.
You guys underestimate the Switch - XB1 gap, particularly, the CPU gap. XB1 CPU is at least >2 x faster than Switch, more like 2.5x faster from some known developers.
Ok, let's take Doom example to see how a MHW port on Switch would run: Doom runs at half the frame-rate and like twice less pixels on Switch compared to XB1 with serious downgrades everywhere. So from this MHW on Switch would run at 12-15fps at 576p with necessarily downgrades everywhere: textures, polygon counts, lighting etc.
And that's totally ignoring the fact that Switch has only 3GB memory compared to at least 5GB on twins consoles. Doom is a linear game so it probably doesn't need 5GB to run on XB1 but MHW is a big open world with plenty of persistent and dynamic data, more so than most open world out there like Far Cry or Assassin's creed. For instance in MHW all monsters have a dynamic impact on the world, even if it's far away from you. They kill others monsters (that you can loot), they leave steps (that you can inspect), etc.
That persistent data is crucial to the gameplay of MHW !!! If you played the game you'd understand ! It is what makes this game so special.
