I remember both my first and second/old main world. Both were mobile 1.2 era worlds (i.e. "Tiny" world size) and I played them in only those versions.
My (supposedly) first world had me spawned in between two of those overground cave-like plateau things, in the middle of a small sandy pit. I don't remember much of it, but I know it had a blue dungeon on the right side of the world and I remember getting DG'd the very first time when I entered it, I remember I was sick and was eating crackers at the time, I was so shocked and my mom was me at that time and I just said "oh I just got killed by a giant flying spinning skull" and I remember she scolded me for "playing violent games" lmao
My second world I remember so much I could probably remake most of the surface of it if I put my mind to it. Spawn was a fairly flat area that I don't remember much of, but I made a small house shaped like a tree and a corridor filled with banners underneath, alongside other houses nearby, such as my first house that had a chinese lantern and was pretty compact. I'll start with the left of spawn, a steep cliff dropping to a lowland area (I had a lot of storage crap and a cave around there), leading into another one of those cave plateaus, steep upwards (once made an artificial crimson there), then leading into a tiny desert with a pyramid and then the corruption with a single chasm pit. After that, a bit of terrain, and a non-hollow giant tree that I used as an arena for mech bosses and so much more. After that, a few more terrain thingd, and a pink dungeon with a fairly simple and open layout, then the ocean. I remember trying to dig my first hellevator near spawn but getting stuck because of water so I gave up at the time but continued on later. To the right of spawn, another cliff, natural but artificially excavated, leading to another one of those cave plateau things, leading to a lowland/dip that had one of the first caves I ever dug and I remember it having the cool stalagmite background and a lot of gems. Above the plateau was supposedly the only floating island in that world. To the right of that, a decent bit of terrain then a small jungle which had a single tunnel that lead all the way to the lizard temple and had enough space to be an impromptu Plantera arena. I remember making a mini snow biome above or next to the jungle with a small igloo and being so scared when an ice golem spawned. After that, I don't remember much of the remaining right side of the world but I think the jungle just ended and went right into the ocean.
The reason I remember my second world so wrll is because it was my main world on my old iPad and I had formed so many memories in it, from my first house, the banner corridor, my first fall into the chasm (and me discovering fall damage), to killing WoF on my first try, to my mech boss fights in the living tree, to finally killing Plantera after so so many tries, to getting the Terra Blade, to killing Ocram, and so on and so on. One of the most memorable things was my first guide, which was named Dylan, and I remember being so sad when spawning WoF killed him. To this day, I don't think I've gotten a Dylan guide yet, strangely, and yes, that one guide single-handedly made me respect the name Dylan so much, lol
Unfortunately, when I transferred my files from my old iPad to the new one (summer of 2017) the world files didn't transfer, only the characters did. So unfortunately, I lost the world I held closest to my heart (and many others), and I remember crying so much about it (especially since chances of me getting it back right now are very low, with my old iPad not being used in 6 years and its battery being crap). This world also had the alpine mountain background (this was wayyy before Zoologist's throwing globes were a thing), so my main world on the new iPad was named "Mountain" as a tribute, and thankfully it generated with the mountain background, the terrain itself was pretty cool and there were a bunch of the mobile-exclusive structures (including a Heart Shrine inside a lone corruption chasm which made it look like a sword stabbing through a heart, and a Jungle Sanctum next to a beehive), and this world thankfully still stayed with me to this day. I wish my old main world would return, but still, this current main world is very good albeit it has way too much corruption and hallow to be feasibly clentaminator'd and I also regret DCU-ing out most of my underground snow biome to make a RoD farm and an artificial underground crimson that were eventually made useless.
Anyways, I hope y'all didn't suffer with reading through this extremely long wall of text and my trip through my own memory lane. Nostalgia is awesome.
ing. Skeletron. I had like 160 HP or something and i had failed countless times to beat him before. But i think i won the battle because i made an arena around the dungeon (i had learnt that from probably one of the first Terraria youtubers i watched, Yrimir), fought him with melee weapons and probably silver tools (i cant remember), and i WON.
. Luckily after finishing my first world world I started watching HappyDays and my arenas became significantly more effective
