i have an oculus rift and i can say nobody would enjoy blockland VR
most games arent much fun in VR mode. sure "experience" programs are cool but most game ports are really dull and hard to play. half life 2 was extremely fun though, and so was minecraft, because it was modded very well.
blockland would be clunky and awkward with the rift, and building impossible. people in the rift are great at aiming and movement, but complicated controls and actions can ruin it. menus can be extremely awkward too, as it feels like they are glued to your eyes.
the best mods create a virtual 3D menu that hovers in front of your characters chest, that can be easily viewed. this would be impossible in blockland.
