I bought Windlands the second it went up and played it for about 3 - 4 hours so far. Really enjoying it, from the little I have played it is currently my favourite VR experience, all I have been doing is exploring, trying to get as high as possible, see how far I can slingshot myself and how far I can jump of the top of places. Not really done any of the objectives though I have got one stone tablet and spent a while trying to get another but failing. There are loads of comfort options however I don't use any of them so can't really comment on how good they are but if you don't like the idea of falling or heights then this will be a problem regardless.
I get massive Metroid Prime mixed with Mirrors Edge feels from this (two of my favourite games). When you get a good flow going it is very reminiscent of the original Mirrors Edge, going from point to point to high speed under your own control and that messing up will bring it to a halt, but a lot better. It reminds me of Metroid Prime's unnique style of exploring areas to get to pickups and find information which unlocks the lore of the world. If you like Metroidvanias even though it isn't one I'd advice you check it out even just purely as a proof of concept for that style of game.
I think it is the best looking PSVR game; everything is clear, bright, nice to look at, the whole Laputa: castle in the sky feel works very well, birds are well sized and are clear, fantastic depth of field which other games really lack. You can see objects far off in the distance and observe the environment which makes it possible to plot paths or see new ways to explore that you wouldn't from close up. The hook shooting mechanic feels natural and you can also use them in a large variety of ways even though it is essentially press a trigger to pull yourself over (not tried the advanced ropes option yet). The jumping is great and the momentum of speed really works for me.
Out of all the games I have played this has the biggest what is possible with the medium coming from a traditional gaming sense. PlayroomVR platform demo was the first that did that for me but this does a lot more, it highlights what can be done in terms of first person games (Rigs did a great job but this more so), whereas many others are slow and clunky in confined spaces this is the total opposite, it shows that FPS in open environments is possible, that first person platforming works extremely well, that exploration doesn't have to be confined to small areas and that they don't have to be in flat spaces.
My only downside at the moment is I wish there was a quick 180 button. Immediately from playing the game I want a Lovely Planet type DLC and something similar to Mirrors Edge Pure Time trials. I also got Tethered but haven't downloaded it yet.
