In my opinion factions would only work if:
1. it was HEAVILY moderated (maybe a new group [FactionMod] )
2. a new multiverse world was created for a much larger wild, effectively removing the issue of there ever being not enough non-claimed land. (factions would
only be creatable
in that new mv world)
3. the price to create one should be very large. I'm talking
at least $200 000, which would limit the amount of worthless, quickly-dying/low players factions, and would encourage people to pool money in for their desired group to become a faction.
4. A limit of up to 5 factions in the world.
*5. Building upon number 4, another idea is to have only 3 preset-by-admins factions, which are all hostile to eachother and are like 3 nations to choose from
ex: Team Rocket, Team Magma, Team Aqua.
Charizard Nation, Blastoise Nation, Venusaur nation.
Kanto Nation, Johto Nation, Hoenn Nation.
( the * cancels out #3 and the last bit of #2 )
