The first sandbox game I had played, even if it is known as a '2D Minecraft' which you don't want to bring it up with the community, because trust me, some players will debate you , it is a fun sandbox Metroidvania & RPG elements.
I had been a player since circa 2015-2016, crazy that it has been 7-8 years, & have been an Adventurer, mixed w/some Builder aspects. The class that I main is the Mage class due to my preference for projectile offense w/ a mix of Summoner, which has been improved since the instances of whips were introduced (my favorite is the Kaleidoscope since I adore the lovely prismatic design, you can get it from the Empress of Light, 1/4 chance of a drop.
The version of the game that I use is the Computer (PC / Steam), the OG as you would call it, and it's easily the best version there is since updates drop on it first even though just to play Terraria, my data for it has to be stored elsewhere since I have limited space and don't want to clog up my computer as a whole.
I had played tModLoader, which is modded Terraria that adds on to the vanilla Terraria experience if you want more things especially when the community is more than happy to provide. As for mods, I enjoy Calamity next to Thorium, Fargo's Mod and Starlight Valley. Honestly, Starlight Valley maybe the mod that would challenge Calamity due to the fact that it feels like an early taste of the Terraria 2, which has been namedropped next to Otherworld (RIP), experience than a modded one as a whole.
Honestly, I don't know what Terraria 2 would have in store but I believe Redigit (Red) has some clues, hmm.
Though everyone in the community knows that the Terraria developers be messing around on the terms of the fabled last update and other things. Let's see if update 1.4.5 is truly the last one or not because all there is that who knows when this massive book of a game will be truly closed?
