Combat, magic, pickpocketing, climbing, being thrown off a mount, cooking, crafting, stealth etc etc etc are all handled codedly.
Where things can't be expressed codedly you'd use the emote command to describe your character's actions, and emotes can also be appended to coded actions. The convention is that code trumps emotes in the
vast majority of cases (generally unless both players agree). So in your example you'd simple type 'sit [thing]' and then you're sat on/by the thing. If a 'power word' were to exist in Armageddon, it'd exist codedly. Out of character communication is typically the very last resort, so your playground scenario is highly unlikely. Power emoting (eg emoting that you do a thing to someone else) is frowned upon. You don't emote grabbing the elf, you emote attempting to grab the elf,or use the coded subdue command. That said, a sense of fair play is good. Try to follow the 'Yes, and' rule from improv instead of just shutting down anything that could have a negative outcome for you. That goes for social interactions too; if you're playing a gullible country bumpkin then let your character fall for bullshit you see straight through. Losing is fun and all that.
I'm not quite sure what you mean by 'talky-RPing'. Roleplay is
mandatory, it's the whole point of the game. Here's the
rules and a short explanation of how we'd define
roleplaying. You can definitely play a character who spends most of their time hunting alone out in the wilderness (if you can survive of course
), but you'd be expected to actually roleplay as an unsociable hunter then. If you're hoping for a hack & slash where your interaction is limited to 'n,n,n,e,kill [thing],loot [thing],n,kill [thing]' then it isn't the game for you.
