But to use Arm terms, I just want to make sure that when there's nothing going on there's something equivalent to to going out and hunting scrab or raptors.I just wanted to respond to this bit specifically.
On one hand, sure. There are things like that. I can't go into detail but they are there. Just be careful as creatures here can be rough on a new character. Very rough.
However, I think it's important to point out that Sindome expects Role Play and things to at least make a little IC sense. So if you are killing rats non-stop, what is the IC reason for your PC to be doing this? It's not hard to make one up that works for your character but having one is important. In my experience saying "I was OOCly bored" isn't enough. It doesn't have to be much but some IC justification is important in my experience.
Also, there are frequently consequences. If your PC kills a ton of Moggleworts they might be attacked or killed o ostricized by others. It could be NPCs or PCs or maybe the Moggleworts gang up and hunt you down for revenge. It doesn't always happen but it can. I think it's important to always remember that there very well might be unhappy consequences for a PC's actions.
Lastly, I feel that grind in Sindome is different from most other MUDs I've played. There's less time spent running the attack command over and over again. But more time spent on planning, socializing, organizing, scouting, writing and more. I find that I am never short of things I can have my PC go and do. There is always more that my PC can do then I have time to play even. But it's rarely just attacking things.
Examples:
Scouting the best escape route from point A where I plan on commuting a crime.
Writing up a flyer that talks smack about an enemy.
Learning the network of rooftops.
Buying a new toy and learning how to use it well.
Visiting Bars and clubs to gather info or spread 'data'.
Hunting a creature for RP purposes 'food, fur, acience, whatever).
RPing a training montage at the gym.
Checking to see what various people in the game world deal in.
Checking out markets for pricing, stock and availability.
There are a ton more but most of my 'solo grind' in Sindome is purpose based. Little things can be done in pursuit of my character's goals that don't need others about to engage in. That's just how I approach it.
Lastly, I want to point out that I've played early morning, Day and late night times in Sindome and I have not once been the only one on. There have always been others to interact with. Sometimes I have to put in a little work to connect with them but they have always been there. I think it's one of the biggest selling points of SIndome. For a MUD there are a lot of players and most of them WANT to interact with other PCs.
Just some thoughts I had! I hope things work out for you, here or on another MUD!
