The Meaning of Life, the Universe, and Everything.
Note: These are all just ideas that I have come up with. None of these mods actually exist, however, it is my hope that someone will make these mods real someday. If you're interested in creating one (or more) of these mods please let me know.
This idea is that players would be able to use r/c drones that will mainly be used for combat and are equipped with guns/missile and/or rocket launchers. There could also be drones that can carry items/cargo so players could transport items without leaving the safety of their homes. The mod would hopefully include land/sea based vehicles too. Obviously a mod like this would be used mainly for multiplayer, but it would be fun to use in singleplayer as well.
Judge Dredd Mod:
This idea is relatively simple: Put on some armor, make/ find a Lawgiver pistol, and presto!! you're now Judge Dredd. This mod (if it ever comes to be) would hopefully include Judge Dredds motorcycle, and new NPCs to improve it even more. There could be be new criminal mobs that will attack you (and possibly try to rob nearby villagers) and there may even be Judge NPCs that will help you take down the criminals. Also there could be new structures that spawn into the world because well the world of Judge Dredd takes place in an apocalyptic future. One more thing: I hope mutant mobs would be added to, because in Judge Dredds world some humans have been mutated into horrible creatures by radiation or something. (I don't know much about Judge Dredd. Only what I learned after spending like 5 minutes researching him on Google/Wikipedia)
This idea is that players would be able to craft tasers that stun enemies and do damage over time. Some tasers in the mod would only be able to be used in melee, some could only be shot at enemies, and the very best tasers could do both. Each taser could only hold a certain amount of charge before either needing a new battery or just simply recharged. For the tasers that can both shoot and be used in melee, they will have two batteries inside them: one in the actual taser and one in the cartridges for when you need to shoot enemies with it. When you shoot the taser only the charge in the cartridge would be used, and when you use a melee attack on an enemy (while holding a taser of course) it would use some of the charge from the taser itself, but not any charge from the cartridge. Also the cartridges would NOT be able to be recharged, once you've used all the charge in a cartridge you simply throw that cartridge away and get a new one, however the melee tasers (and the melee aspect of the dual tasers) could be recharged. I was thinking that once a cartridge is used it should automatically drop on the ground, and you could put a new cartridge in by either crafting the taser with a fresh cartridge or by pressing a 'reload' key. As stated before enemies attacked with a taser would be unable to move while being attacked (and for a duration afterwards depending on how long they were being tased) and they would also slowly take damage while being tased and perhaps take even more damage after being tased (for a time)
Harrison Ford Mod:
The main point of this mod would be to allow players to become some of Harrison Fords iconic movie characters such as Indiana Jones and Han Solo. It would just add in armor weapons and tools based on some of the characters Harrison Ford has portrayed. For Indiana Jones there could be a Fedora (hat), pants, maybe a jacket, a satchel, a revolver, and of course a whip. Im not sure if it would be possible but it would be awesome if the whip could not only be used as a weapon, but could also entangle enemies and even be used to swing across things. For Han Solo there would be Hans jacket, pants, shoes, and of course a blaster pistol like the one Han Solo carries.
Grim Reaper Mod:
This idea is that players would actually get to become the entity of death (grim reaper) himself. There would be new clothes/armor so you could look the part, new weapons (scythe) but the main point would be that it would hopefully add in an aging system where the animals and villagers age and eventually die (whether its due to age or getting killed by zombies or whatever) and after they die, you THE GRIM REAPER can collect their souls to get stronger and gain special abilities such as teleportation, speed, flight, pass through solid objects, etc. And you could put souls in your scythe to make IT stronger (i.e. do more damage and get enchantments)
This idea is that players would actually get to become Raiden in minecraft!!! This mod would add in a new set of armor and give you special abilities/effects such as the ability to call down lightning strikes on command, ability to fly , give you speed, strength, resistance, ability to teleport, etc. Also your powers would be weaker in other dimensions: you won't be able to teleport as far, your lightning will do less damage, won't be able to fly as fast, etc. Maybe add config. options for that in case you don't want your powers to be weaker in other dimensions.
Jason Voorhees Mod:
A mod that would allow players to become the infamous murderer jason voorhees (hopefully add in jason voorhees mob to fight as well) There would be a new set of armor and once players became jason they would gain special abilities: Regeneration, Strength, Resistance, and extra health. My idea is that players would have to fight the jason voorhees mob, and once the mob is killed it would drop the armor and a machete. Basically once the jason mob is killed the person that killed it replaces the mob (or player) as the new world/server murderer. Another idea is that the more villagers/players the murderer killed the stronger they got, and as they got stronger they would gain new abilities and the abilities they already had would get stronger. The armor would never break, and neither would the machete so to keep them from being too overpowered the armor would have low protection and the machete would have low-ish attack damage (6 damage maybe?)
I started making a mod called dronecraft and searched the name to see what would come up and found here. Your idea sounds abit like what im trying to make so if you want to see the mod search it on curseforge! I still have lots of content to put into it but the basic jist of it is there. It will include item transportation and automation hopefully.
