The thing is, regarding interest, the game does nothing to really hold it. It's a boring, repetitive gameplay consisting of leveling up, grinding, leveling up again without any semblance of a storyline (just an
example of a mechanic that could break more of the boring aspect, not necessarily something that could be implemented right now) that can really hold your attention. It's barebones, even if I feel nostalgic towards it.
Yes, originally, the interest was meant to be social, but now at lower levels, speaking about my level 20, 27 and 31 profiles I have, you're relatively alone. There is no social interest. You hardly meet any people, the chats aren't active at all, or are hardly active, and everyone is huddled in the big clans and that is it for the most part, especially for EU 2 where I'm at. Getting into the politics seems tedious, because you have to grind all the hell up to 50-55 too. Of course, I'm changing the subject, but regarding interest point, the game doesn't really create it at all.
This part of the evo update does not feel that well planned. As Queenie mentioned, it's funny watching a baby dino fight a fully grown alpha. It would've been better if you changed with the environment rather than just evolving way later on. The dinos at level 30 change, why doesn't yours for example? They could've still pushed back the evolutions instead of throwing them far back. To max players, this part of the update wasn't even a concern, nor did it change much or anything.
Dragossauro's idea is also not that bad and it's something I've thought too. But I'm not sure as to how that evolution would really look like because the lvl 14 one was supposed to be the awkward transition one, which is why I hadn't really suggested it.
Those are my general thoughts and impressions of the game and update. I liked it when I was younger, the rangers on my account are from 2012 and I still remember the potions we used to have very early on and the baby dinos. But it's not in any way a fun, engaging experience to create long-term interest from a new player perspective or a low level perspective.
