So after rewatching the Blade movies (just 1 and 2... we don't talk about the other one), I've been spitballing some ideas that could be implemented into the next Blade game.

Here are some ideas I thought of:

1. Have a morality system similar to inFamous and Dishonored. Have Blade struggle with his dual identity of being half-human, half-vampire. Maybe throughout the game, have Blade make decisions throughout the story that either play to his vampirism or humanity, and maybe gameplay decisions as well (i.e.: suck the blood off of human victims, try to "cure" vampires, etc.). Maybe also have separate skill trees for vampire and human sides; if Blade embraces his vampirism, more vampire-related abilities will be unlocked, if he embraces his humanity, there will be more skills unlocked that relate to his martial arts, weapons, etc.
2. Have the basis of the plot be about vampires "evolving" (Similar to the plot in Blade 2 of vampires mutating into the Reapers). At day, vampires hide out in nightclubs and more human-like establishments, and maybe wear sunscreen for good measure, whereas at night, vampires lurk around the streets of Paris alongside the more "evolved" vampires. Make it like Dying Light where the vampires during the day are more or less cannon fodder, but at night, vampires and "evolved" are harder to kill, but yield higher rewards.
3. Have Whistler in the game... non-negotiable
4. This point may be a bit biased cuz I'm a car guy, but give Blade some transportation, kinda like the Batmobile in Arkham Knight. Give him an unlicensed '68 Dodge Charger like in the movies, or since this game may take place in modern day, give him a Cadillac CT5 Blackwing, or C8 Corvette... or since this takes place in Paris, give him something European, not too exotic, not too civilian (something along the lines of an Audi A8, or BMW M5)
5. Have the combat be a mix of Insomniac's Spider-Man, Arkham, and God of War. Implement a control scheme that allows Blade to seamlessly switch between sword, stake, fists, gun, etc. Not entirely necessary, but also include a combo system that rewards players for a higher combo, like giving Blade the ability to do an instant takedown if the combo is high enough. Also, include a "rage" system that has different versions like in God of War: Ragnarok. Ex.: "Biter": Go towards an enemy and instantly suck their blood for an instant kill while gaining back health, "Hunter": Quite literally rip and tear through enemies with your bare hands, "Gunslinger": A mechanic that allows you to highlight enemies, and use your gun to insta-kill them, similar to the Dead-Eye system in Red Dead Redemption.
6. Going off of points 1 and 2, early in the game, have Blade be bitten by one of the "evolved" vampires, leading to him slowly being infected and becoming one of the "evolved", lending itself to the morality system. Make the plot of the game like a race against the clock, like Arkham City.
7. With the boss fights, have Blade "bite" them when he defeats them, leading to him unlocking new abilities (i.e.: turning into a swarm of bats, having Blade's trenchcoat transform into something like Dracula's cloak where he can be virtually "invisible" or absorb any and all damage, etc.)

These seem to be all of the core points I thought up so far. Feel free to add more ideas if you want. I'd love to hear your thoughts.

(Full discloure: I came up with the majority of these ideas while I was in the shower today)
