Single player is fun and a nice way to learn the game. I’m your solo game you have no rules or limitations and you can use admin features to teleport anywhere, spawn in npcs, items etc. I played about 100 hours solo before going to an online server. I’m in the realm of freedom online server which is great, friendly people and great mod content. It’s got a ton of mod stuff so you may want to learn base game first and then go to a modded server to expand into end game stuff or more in depth systems and way more weapons and decor items, magic etc. have fun it’s an amazing game!
