Just a time ticking incentive for whatever you can think of !
Having a quest like deliver a hot pie... but making sure it's delivered quickly so it stays hot... (as a try out for time ticking quest ?) Imagine someone's making a long sending when you're supposed to give the pie... what would you do ?....
Or a kidnapping for some dark ceremony, and if PCs are too slow, thay actually fail the quest if the kid dies... even if they beat the hell out of the baddies.
Or "help my friend didn't take his pack of bubbleberries to explore that underwater depot, he won't make it back unless you're in time..."
Tic tac tic tac tic tac.... no healing break ? Ouch....
Those "afk", "brb", "forgot to buy something", "nature calls"... won't like it though... :twisted:
How does that sound ?
