Hammerbro
Fill in Here: Companion game to Megaton
Factions include: -Mushroom Kingdom -Koopa Kingdom -Boo Kingdom (from what I saw, King Boo is an associate and not necessarily a subject of Bowser) -The Shy Guy Kingdom (scattered throughout a series of pocket dimensions, lairs, etc. While they occasionally do mercenary work for Bowser, Smithy, Wort, or other enemies of the Mushroom Kingdom, they're isolationist otherwise.) -The X-Nauts (these guys are supposed to be "new" and all technological and all). -The Smithy Gang (although they're at risk of being Tatanga'd).
