So I was thinking
This doesn't deserve just an anime
I want to see Valkyrie Core: The Game.
(Funded by Gilgamesh again, of course, no need to worry about silly EA or other publisher shenanigans)
Genre: Mecha TPS, like Armored Core, with RPG elements.
Features: Massively multiplayer co-op (offensives), PvP matches (tournaments), and small-squad co-op for regular missions.
The Offensives would be huge-scale battles with thousands of players versus hundreds of thousands of AG at a time. Would probably need to delay release for a few years (or decades) for the hardware to become available, though. And Gilgamesh's funding again, for the servers.
RPG elements would include full customizability, of your stats, loadout, and looks. Could allow for either full frame customization or lighter customization but opening the door for user-created base frames, as sort of a 'made by the community' thing.
Stat increases and loadout options would allow for many different styles of play and dakka flavors, from melee focused builds capable of taking down elite Types to builds that focus on More Dakka and auto-targeting to clear the skies of enemies.
Teamwork would be heavily encouraged in offensives, with overlapping shields making it much easier to survive against swarms, and other formation bonuses.
Goddamn, I want this game now
