I saw someone play a bot about role playing. It have classes like mage, assasin, theif, knight,, etc
Like ! class <race> <nick> to make a account to the bot
when we want to fight, we use !fight <nick> to start the fight. !folder to see the weapon we have !<weapon given by the bot> !<combo> combination of weapon give some combo
Difficulty in making any script depends on the amount of detail and options/features needed. For a role playing script, you can have a very basic one done in a few minutes... or one that is very in-depth which requires months of coding and story writing.
