I really want big wars. Outlaw dynamite and such, but a team of crossbowmen and swordsmen against a similar team would be awesome. Strip everyone of items during the match and give them either a basic shield and sword or a basic crossbow, maybe both. Fight off somewhere in the wilderness or a seperate area.
Before all that, though, set some kind of team mechanic. I hate the volcano with any more than just me because the balls fly everywhere in there. Definitely would be nice to stop damaging people you don't want to.
Then it would be nice to have a basic record of stats, like displaying your total arrests, total captures, total kills, etc.
Fill in the empty spots in the buildings in both port and starboard and add stuff to the already existing areas before expanding the world at all. Maybe up the number of rocks out there.
Some method of getting stronger over time, maybe just have it be so you can wield stronger weapons rather than just increasing strength. More varieties of weapons, as well, or at least more variances on already existing ones. Like a crossbow with a 3-shot spread, or a sword with a short range that attacks faster.
wow, brainstorm.
