I like almost everything on No Man Sky, except the challenge is just not there. You can play on "realistic" mode but this just means more grind and downtime on hazard planets, not exactly a more skill-based gameplay.

After playing the first 5 hours of No Man Sky I pretty much saw everything the game had to offer and what was left was repeat the same routine of land-mine-take off on different planets. There was never any specially challening obstacle or anything to look outside a bigger ship and inventory.

My biggest wish for No Man Sky is a gameplay patch which gives you a progression and something to look for.
