tldr: All 8 battlers pay $1-2 worth of fuel to enter the arena, the winners (1st, 2nd & 3rd) walk away with e.g $8, $4, $2, $2 (1st gets 4x back, 2nd gets 2x back and 3rd & 4th basically get cost back).. numbers here are just an example, but you get the idea (cost should be very low).
This would make the arena so much more exciting.. it will have the following benefits:
A) More people would want to play arena to have the chance to win $$ every game (just look at how many ppl show up to tournies vs. regular everyday gaming)
b) It won't cost the treasury anything
C) It will act as a fuel sink, helping LAND value go uppp ^^
D) It'll give more purpose to Zero and drive people to make fuel to sell it
Bonus idea: there's a grand monthly tournament day where cost and rewards are 10x inviting the best of the best to compete and win.
Also this is my first week playing so
