I noticed another thread somewhat similar to this but a lot more specific then this thread. The point of this thread is to suggest "incentives" to help entice PVP'ers to well, PVP more.
My thought would be a specialized Arena. In this Arena you would be able to spar player vs player for various items. Here you won't actually "die" but when you lose all your life get warped out of the arena and the item designated from your inventory for the dual be removed from your inventory. Obviously within the "arena" when you're not fighting you won't be able to be killed. In a game like this there should always be a "protection" area in which you can't build in but will have the ability to hang out with others. Also within the radius of the Arena outside you won't be able to build on. I also think it would be logical to have yourself be able to travel to it via the "travel" button.
Such as let's say someone dualed and offered Tin Vs. Copper. The Tin guy ends up winning and makes out with some copper. Of course a bigger variety of items might make this more interesting but uhhh. Yeah.
This idea sort of came from FF3. If you guys remember in the basically 2nd half of the game where instead of the opera house it's exchanged with an Arena. That was mf'ing sweet. Something like that here would be pretttyy awesome. I might expand on this arena idea in another thread if I get the time to. But yeah.
What do you think would get you or other's motivated to PVP more?
