B2P with a trial sounds nice. The cash shop approach makes sense if it's sticking to b2p, but I hope it doesn't end up as the only way to get cosmetics of note. Would be nice to have it as an easy way to get nice looks, but reserve the best for in game achievements or crafting.
I'd like to see supply chains. Perhaps food is a nigh mandatory buff, so a settlement worth its salt would want to provide access to food, which could require sums of meat and wood for players wanting to build it up to gather. Perhaps metal and leather brought back could be used to make equipment which not only goes towards arming players, but maybe funding NPC guards to keep it safer overall. Little things like that could make it very easy to set goals for contribution when hopping on for a bit, or give cause for resources to be fought over besides simple expansion.
Really interested in this MMO and seeing how all of its parts end up coming together. Also wondering how the community will take to being split across three different subgames. Just seeing how that ends up coming along is worth following this to me all on its own!
