So ... this is my favorite game so far, there's no way i wouldn't recommend it.
Terraria is a great 2d sandbox game, with a lot of tiny rpg aspect, mechanics to use, content to discover (may it be biomes, weapons, monters, bosses, resources, ...), and, thats only from the vanilla, the game also support mods which improves a lot the gameplay experience.

Edit:
It's 2021, It is still one of my comfort games.
