can I please be in there as a random space marine (I'lll give you the textures, meshes, etc)
suggestions: you should make it so the map is split up into different provinces for different parts of the forums, and certain parts could have special things about them, the pioneers guild would be cool it could have different cities for differetn mods (not all mods just the ones people cared about) and each city could be like a city in that mod, and the troops you got there would be from the mod, and the units spawned from the city would be from the mod, ie: the Warhammer mod (if Ursca lets you) could be the city gagrim is making now (Ostland I belive) around it 1 or 2 units from 2 factions could spawn so like a empire halberdier unit, or empire patrol or whatever, could spawn and an undead host could spawn from the city, the two parties would war with eachother, and if you chose the parties of other certain mods. and then from the tavern you could recruit empire halberdiers and swodsmen, and maybye zombies, or you could get zombies from a special charecter in ostland.
-To include mods not on TW you could have an island called MBX, and you could put MBX based mods there and it would be basically the same as the pioneers guild, you would have to take a boat from zendar to there.
-For Main factions you could replace swadians with modders and admins etc *"the forces of 1337nes

". and veagirs with flamers, hackers, noobs (not newbs), those bastards who talk like they're on ****ing msn (they could have weapons that shoot out endless streams of "omg cuz ur likez gayzorz roflez" or "this mod iz sux you y mod mak vis???!111"), those people who like to rain on everyones parade *erhem cough cough
http://mbx.streetofeyes.com/index.php/topic,155.240.html, etc * "the forces of um... i dunno

".
-you should also make it so instead of weapon smiths, and armorers, etc you should change them to well known/proficient modellers, ie: grim reaper the gunsmith,Pope the poly master, etc.
-certain parties, like flamers could be invisible, and pop out of no where to attack you, they could ride on steeds that are flaming (via particle effects) swear words, and they could wear shirts that say "I am uber"

"
-Hackers could possibly be a rather weak party that spawns parties called pop ups, spyware, spy warez :p, virus, and pron, pop ups could be invisble parties that have 50 or so troops with the lowest stats possible, no armour, and could use sticks that do like3 damage,spy ware, could use a script that took gold from you every tim ethey killed on of your troops, spy warez ( iknow this is random) could use a script that copied your party and attacked you with it, for the virus you could just battle them in a map where the virus troops are up on top of a hill with missile weapons, andyou spawn in water, and thers a long walk through water before you reach the viruses, you could change the look of the water in that scene to binary or something. pron, could be the same as spyware, but the troops are more skilled.
-the anochronists guild could be really random, evry troop could have like random equipment, like fishes, and lots of colourful stuff and the map could be technicoloured.
I have more random ideas but I must go to school, I might be willing to do some modelling for this, but I still am working on 40k mod, and a mod for school.
