I would love a New World Forever
I've never been a WoW guy, but the whole hype around WoW Forever got me quite jealous.
Now imagine for a second that we had a New World Forever, with a much slower leveling experience so you could enjoy every bit of side questing and there is life in each town including low level ones. Where crafting and gathering plays a huge role even at low levels. And you take your time leveling up and build up your forever character.
The end game has always been NWs weakest point but the main quest line and the first time leveling has been magnificent. I know over the years they sped up leveling quite a bit and it did help them get more players, but I'd have loved a slow and steady version of the game.
