Been playing for about a week now. Yesterday I switched from PS4 to PC, tried playing Hardcore but could only find 2 servers with almost no one on and wasn't able to become part of a tribe. After dying at level 16 and being unable to reclaim my home I decided I'd come back to Hardcore once I've found a small tribe to belong to.
On Ragnarok I established a thatch hut and was continuously bombarded by larger and larger bird-life, which resulted in an excessive aversion to birds. First it was those small, seagull-like birds stealing my berries, damaging me, and being annoying. I had to struggle to build my thatch hut while dodging the bird. Once I established the hut I was relatively safe and was able to craft more spears, a bow, arrows, and some clothing.
By this point my beach started to be over run with very large, eagle-like birds that killed me a couple times. It was this one, specific male bird that was harassing me. Finally, I had enough and crafted more arrows so I could kill it. It was not even close to enough. Hiding inside my base without arrows and no resources to make more, I started attacking with my spear at the bird head sticking through the wall and doorway. It fled twice and returned from the damage I inflicted and on the second time it returned with a female. The whole ordeal was exhausting, but I had bird for dinner!
I earned about 8 or 10 talons from these giant eagle-looking birds that I was only able to kill by stabbing them with my spear from the safety of my hut. They kept coming to attack me in pairs, male and female.
A couple days later, maybe a week, my hut was visited by a Carnosaur. We were good about co-existing. It only chased after me twice and many times my triceritops neighbor scared it away from my hut. Once, however, when I was running from the Carnosaur and made it to the safety of the cliff my base was on, where I could not be reached, I was attacked by a f***ing bird that knocked me off the ledge, into the water, and subsequently eaten by the Carnosaur.
Finally, it was reaching the evening in real life so I decided to make the base level of a wooden castle-tower, which would be my next base. After its completion and the dismantling of my prior base (same location), I locked my doors and logged off.
