The things I want are too hard and boring to explain. I'll try to tldr.
1) One is for open world RPGs to stop having short sighted enemies. It's weird exploring a big open world and enemies ignore me because I'm 30 feet away or whatever. Get 24 feet away and they attack. I'd like to have enemies spot you from a distant hill, when you can't even see them. And they will come to ambush you. There are some FPSs that have done this for years, Arma, STALKER, etc. But RPGs not so much. It would make magic and invisibility actually meaningful. As well as illusions. (EQ does some of this, and Arma)
2) I want an RTS but with an infinite map. Minecrap and various other indie games have infinite maps, the aforementioned Arma had infinite maps in one case. With RTS games they are all set on a small 32x32 map or whatever. I don't think graphics are an issue, I think the big issue is hundreds of individual AI units all having to navigate to wherever they need to go. It kills CPUs. But there has to be a way to sort the work into batches or something. I don't need 100% realtime reactions, just real time control. In other words, select a group of units and click 60km away, I don't need it to calculate the path instantly, which is how I think every RTS currently works. What it should do is just start running in that correct general direction, and update the navigation as it goes. The CPU isn't always at 100% so it has to find the right time to do stuff like that.
Also it doesn't need to have deformable terrain. I love that but it kills the CPU even more. What I really want is an RTS that doesn't end after an hour. It goes on and on. So you build your initial base and defend against attackers. Once the defences seem sufficient, you send squads out into the waves of enemies to set up other bases. And there should be multiple resources scattered around to encourage that. And I'd make it so that the enemies start as little critters that your guns can take down easily, but it progresses to end up with huge things that need tactics to take down. There is a mod called Nuttyb Raptors of Beyond All Reason which itself is a mod, which kinda does what I want. But it's still on a small map and it ends after an hour or whatever. I picture a game with a huge world with events and stuff on it to keep the player exploring. Something like Heroes of M&M or a 4X.
Also it needs to have the artillery from World in Conflict. Without that, why even play an RTS?
3) A modern version of Police Quest. It's not even a good series but I love the idea of being a detective/cop in a game. I wanted to see it done in a modern 3d world like GTA. There is a mod now for GTA5 which lets you play as a cop which is part of what I wanted. The rest just needs to be some kind of detective adventure that involves actual detective work, not going where you are told and following the glowing yellow UI.
4) A Predator game. I thought of this after playing Crysis for the first time. I wanted a mod or a game where you sneak around the treetops in invisible form. Stalking your enemies. Then at the right time you attack with badass weapons and heroic melee attacks. Since then I know there has been a Predator game or two but I didn't even bother looking at them because I know it will suck.
5) Animal RPG
You start as a worm in a huge savannah. And you have to eat microbes or something to level up. At level 2 you become a snake and have to hunt mice. At level 3 you become an armadillo or something. Eventually you are a wolf and lion, etc. And you get to hunt as those animals would. Enemies react to you from miles away, and can smell you and hear you. So when you become a stalking cat or something you become silent and can sneak up on stuff. What I hoped was that it would look like real life, but the gameplay would be kind of action combat-like, only complex. Also maybe the player could shapeshift back to previous creatures to help with new enemies. I haven't thought about this much, I mostly just like the idea of an RPG in pretty outdoor African savannahs or something instead of always being in church basements.
p.s. Spore was not inspiration for this idea, that game I try to forget. The inspiration for this idea is a game which lets you become creatures each with their own unique abilities:

6) A fighting game based on an old classic called Panza Kickboxing. Realistic combat not like Streetfighter or most fighting games. And you customize your character's moves. I think the best thing about that game though was the control method, and it's never been used since. I'd really like it in 3D though and making that control method work in 3D would be a challenge. But I think I know how to do it and it would be better than any other fighting game I've seen. Realistic fighting simulation in realtime and requires reflexes and skill. There is a recent game sort of similar called Absolver but not quite what I wanted and it wasn't popular. I would like it similar to that.. only good.
7) An RTS with a commander like TA/SupCom, only you level up the commander further and further like an RPG and it becomes super strong with long range abilities and stuff. This idea was a lot more interesting and original when I first thought of it, since then there have been a million Diablo clones that kind of already do what I had in mind. Grim Dawn etc. Although they get boring fast for me. I'd enjoy the fighting a lot more if it was only done to defend stuff I am building.
