Just saying, there should definitely be something regarding the people in the Nether. i.e. some dude survived on shroom stew, and stuff,
the fact that he is a drug dealer is really funny, also I kind of wish that you did not add in the pigmen thing, after all, they don't actually do that in the game (but I guess they do tend to wander towards player-created areas so idk. The movie was good, and overall I hope that you bring in these things by the end of the series.
1.) a wither (used by the players or the antagonist to destroy the players (the wither destroys buildings and everything it comes across, also multiple withers can be spawned at a time) or used by the players to destroy the antagonist's building) this would hopefully be either used towards the end at the climax, during the big war with the players of the server, or by gaylord when he goes through the nether, and activates it there (where it destroys the awesome city, see #2)
2.) The Nether, I want to see a city re-built in the nether full of all of the players who were sent there. It would be awesome to see a resistance there, especially if it's frigging awesome (they might be able to get the people back to the real world by entering the Milk Daddy's escape portal, Or gaylord sends that one awesome dude (formerly wearing CSI glasses) to the nether where he unites all of the banished players, and gets them to pwn gaylord, and look for another exit.
3.) TNT cannon, it would be cool to see a full-scale attack from the people in the Nether. THis would mean that they build TNT cannons to fire at galord's huge castle, while the rest of the players actively charge at the castle, at the same time, gaylord creates all kinds of mobs(this would be outside of the castle while they are still charging), and then when they got inside of the actual castle (after breaking the gates with the TNT cannon, there would be really freaky traps (i.e. the passage closes behind the few that made it into the castle, and 100,000,000 NPC villagers are spawned in the long cavern-like passage, (8 blocks high, 8 blocks wide, but very very long) that they are in, along with one zombie on the other side of the huge cavern-like hallway, that the players don't know about. THen, after around 1 minute, and a few screams from the villagers, the players see the horde of infected zombies (zombie villagers) coming after them, and gaining in numbers by the second) THAT would make this awesome. (and of course, Milk daddy, (who does not agree to fight against gaylord because his life is perfect as a drug dealer) comes in just as they are about to die, and throws potions and golden apples that cure the villagers, not to mention the possibility of an iron golem)
and of course at the end they make some kind of bet saying whoever wins in the duel (noobly vs gaylord because everyone else is either dead, and on the other side of the map (from respawning), or unable to enter the area) gets server rights
THAT WOULD BE COMPLETELY AWESOME
