Arena fix

[Omnirizon]

how but just getting some gold/gems/items that can be used in anyway the winning nation likes. This is very easy to balance the power of.

Giving a unit forge bonus or teleportation has unit*prize interaction effects that cannot be controlled. For example, a unit with no or little magic isn't so good with a forge bonus, and a unit that's good for forging would not benefit at all from teleportation. Advertising beforehand what the bonus will be will invariably end up in some bastard sending a unit good at killing things that benefit from that bonus; even if that particular unit he sent will not benefit so much, at least s/h/it gets to kill many of the other players units.

A liquid currency like gold is easiest to balance. Some random gems or items that are the winning nation's to keep would add flavor and make the arena worthwhile.
