An idea I posted on the Discord, but I want to see what people think.
G. I. Joe video game.
Half-way point between a Call of Duty clone and an MMORPG.
Each player / account can have up to five characters. You can switch off who you're using as your main character, with the rest being computer-controlled NPCs in missions where that option is available.
Each character is one of three classes: Sunbow-era Greenshirt, Sunbow-era Sailor, or DiC-era Paratrooper. Each class starts with a slightly different skill set, and a different preferred primary weapon.
When a character is brand-new, your options are deliberately limited. You can pick a male or female body template (a la Hero Machine, for those who've used it), their race, their code name, their file card bio, and some minor custom features. Each brand-new character can also use 1 "primary" item and 3 "secondary" items at a time. Primary items at first are the XM-103 laser rifle and the class preferred weapon (M-16, MP5SD, Pump-Action Shotgun, respectively). Secondary items at first are the M1911 pistol, combat knife, smoke grenades, stun grenades, and high explosive grenades.
As you complete missions - either sandbox missions, event missions, or campaign missions - you gain experience *and* boost whatever skills you used during that mission. For example, if the mission had you flying a helicopter, you'd gain in "Helicopter Pilot". The two skills with the highest point totals are your primary and secondary MOS skills, like in the file card.
Gain enough experience, and you level up. This increases the customization options for your specific character, your character's rank, and the amount and type of gear that they can use.
Every so often - say, once per season or even once per major release - there could be a special event in which the winner can get one or more of their characters realized in plastic form and officially inducted into the toy line.
If this was a real game, who here would play it?
