But this still presents an issue that the game ends up being played alone if you don't have any friends with a common interest in this game and matching modpacks. This adds hundreds if not thousands of features. The vanilla game doesn't hold a candle to Terraria's end game, but the Frackin' Universe modpack exists to remedy this problem. If you haven't played it, it's fifteen bucks and the vanilla game is well worth that price alone.
Have you ever played Starbound? It's Terraria-lite except you can explore other planets and just the entire universe in general.
