Ok so this started off in my head as a joke but I think it’s actually genius.
It’s a little crazy that you need to get someone to cover your portal fueling for you if you go away on vacation/holiday out of town for a week (or somewhere with bad internet etc). Like a job! So, introducing: vacation days!
For every 10 hours of playtime you get 1 hr of vacation time. (Ratio negotiable what do you guys think) Like at a job! Anti-idle requiring an input of any kind once per minute to prevent (or reduce) abuse. When you turn on vacation mode, if any of your portals hits empty, the system consumes one hour of vacation time and adds 1 hr of fuel to all/selected portals (I’ll leave it to the community to decide that one)
Could people use vacation time to save coin? Yes but ppl do that irl too, it’s their choice, but then they wouldn’t have it when they need it.
