I am liking the sound of where things are going, especially with random events etc, after all the more that you can be surprised whilst harvesting etc, the better the game will be.
I'd love the seasons to play a real part in gameplay as they would in reality. For example, while weather itself need not be implemented, you could use weather based flags to make certain events show up more often, for example a thunderstorm would be more likely in summer or autumn, rain would be more likely in winter or spring, and forest fires would be more a risk in summer.
likewise, it would be cool if harvesting could at least vaguely reflect seasons, for example in some seasons some crops are harder to find, for example maybe wheat is more common in summer and autumn, while mushrooms and berries are more common in winter, and flowers or flax are more common in spring.
I also love the idea of randomising monsters a bit and having a few stronger monsters kicking around.
Uncharted peak used to have a really interesting three tier system. You'd get normal monsters, like seagles, alligators etc, then you'd get stronger monsters with a suffix such as rabid seagle, monstrous aligator, viscious goblin etc, then you'd get even stronger ones with both a suffix and a sirname, like rabbid seagle flock leader, evil alligator, maneater, dire goblin champion etc.
There were I think two five or six suffixes for each monster along with two or three names, which meant lots of monsters.
Obviously this is a rather complicated generation system, but I'm personally always one of adding extra information to anything and different types, since it always makes the game feel fresh. Look at the wastes as a great example.
You don't even have to stop at different types of monsters either, you could occasionally create other objects that earn an extra description, for example, your bog standard cooked salmon could just earn you five energy, but delicious, or succulent or tender cooked salmon could earn you 7 or 8 energy, likewise, when item crafting gets into the game, why stop at just making a bronze scythe when you could make a balanced bronze scythe, a well crafted bronze scythe etc, since after all, just because two cooks, or smiths, or tailors or whatever have the same basic recipe, that doesn't mean the product they create will be of the same quality?
obviously this is getting complex, but hay for my view the more complexity the better.
As far as the castlevania area goes, its a little difficult for me to suggest anything for it when I'm not %100 sure what exactly it involves, I know it involves Dalgrim's lord's castle, but is he a good or a bad lord? heck at the moment for all we know it's much like that other castlevania and full of vampires and such .
So, it'll be easier to suggest when we know the location a bit more, but I'm personally really looking forward to seeing it.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
