To be honest we're all thinking that deepworlds problem is the lack of updates but no that's not it. We all played deepworld for a long time, we have everything (or mostly) there is, and we've done everything (or mostly) that it can offer. BUT !!! If you're a new player there's a LOT of content that you need 100-200h+ of gameplay to achieve.
So deepworld needs new players and here's the real deepworlds problem --> Deepworld isn't new player friendly.
And that's not because of the community or whatever that's because there's nearly nothing that a new player can do to compete against others that have played for a long time. For example new player can't do anything even in a temperate biome, there's a lot of dungeons he can't raid, there's nearly no 'random loot' from which he can get building/utility items, and obviously he won't get any crystals while competing with others that have perception lvl10+. And if a new player can't get crystals he can't progress in the game ( yes crystals are the first step of progression in this game). If there's no progression game becomes boring ( or at least there's no meaning in playing it) --> new player leaves the game.
we need to make a new player friendly environment in the game.
For example I recently joined an old pre alpha/beta world ( I wasn't playing back then so I can't tell) and was amazed how much content there was for new players, no dungeons, nearly no protectors at all, A LOT of randomly placed crates/sacks with stacks of building materials next to it.
So here's my advice on what you can do. Maybe you should make new category of worlds that can be joined only by new players and this worlds are the same as alpha/beta worlds.
Would like to hear any other suggestion that other's can add to this.
