What I would want from a Cyberpunk RPG destined for a 2015 launch:
1. Graphics optimized for the PC. Since we are talking about 2015, that is the year of nVidia Maxwell or better and Intel Skylake processors. This game should not waste resources on poor programming and be able to utilize 8+ CPU cores and 4 GPUs to prevent any bottleneck people with high-end PCs may have. Since this game is also being made for next-gen consoles, and since those consoles use PC hardware, this should be easy. I don't want it to feel like Deus Ex: Human Revolution, knowing that 4 years ago, Crysis looked better. Granted, I loved the story of Deus Ex.
2. Better physics than games out there today. Flowing hair, clothes that move with your movements, destructible buildings, water and gas with volume, not just effects. Best if you could program it for DirectComputer/OpenCL to make good physics universal for nVidia, AMD, and Intel people.
3. A soundtrack that surrounds you and mystifies the environment. I'm thinking Deus Ex, Assassin's Creed, Mass Effect soundtracks. Although of course with a cyberpunk theme to it.
4. Multiplayer, good multiplayer. Not just every man for himself, or team vs team. Have something with a cyberpunk theme like: Infiltrate an enemy's base to upload a virus to that enemy's mainframe. The mainframe holds the minds of the enemy players who use bodies that merely act as avatars. For this reason, when you kill an enemy, normally he can respawn in a clone. But upload a virus into their mainframe, and you control their minds, causing game over for the enemy. You can't resist when an enemy has your mind.
5. Themes I want to see: Mind uploading, mind hacking (centered around a theme of major corporations/governments moving to control large populations via their brainchips), mind-mind communication networks (like they did with those rats a few days ago), really big guns (like tactical nukes for insane fights, plasma rifles with really cool looking plasma, fusion cannons that spit out big balls of god-like light that incinerates everything it touches), multiple conspiracy groups players have to watch out for, multiple plot twists (your best friend/lover turns out to be corrupt and betrays you), moral questions that constantly hit the player in his choices (like Deus Ex or, better yet, Heavy Rain), a feeling that the end of the world is upon us, at least one nuclear blast/asteroid strike with a blastwave that tears buildings apart and fries the flesh off of unaugmented citizens (like in Terminator 2; you should be able to witness all this and survive; also, this should serve as the best demonstration of next-gen physics processing), mind-hacking nanites in gaseous form launched into crowds like tear gas, inability to trust not only anyone, but yourself as well due to the mass spreading of mind-hacking technologies. Are my senses correct? Am I in control of my own thoughts? Am I just a brain in a vat right now? Make the player think he is crazy, alone, and with no one and nothing to trust.
6. Use of vehicles: Able to use fancy hover cars is a minimum. I'm talking more like future tanks (hover tanks), mechs, or better yet, some kind of futuristic air/spacecraft. Could be used in single player and multiplayer. Of course we are not talking about far future stuff here, so it will probably be like a chopper or a VTOL.
7. Robots, and lots of em. Make them realistic looking androids (who is human and who is machine becomes unknown until it is too late), make them smart, make them in positions of power, and make them hackable.
8. Holograms, AI smarter than humans, and lots of tricks on the mind.
9. Asian (Japanese, South Korean, Chinese), American (United States), and European (Britain, Italy, Germany, France, Switzerland) conspiracy organizations. Theme areas to Asian, American, and European looks, lifestyles, language, and attitudes. Large world governments, like in 1984, to simplify this process.
10. Continuous end-game play. Either have a final boss, after which you have different missions players can continue playing (updated via DLC, paid or free), or just end with constant zones players have to work through, improving stats, equips, and skills. Prior option is probably best. Don't let all our work mean nothing with new DLC. Allow us to keep our augments and just explore more stories.
11. A really advanced character editor. I'm thinking EVE Online or better. Make my character lots of polygons, sexy style (for women) or manly style (for men). Able to make my character look American, European, or Asian. Able to make female and male characters or various builds: from small and petite women and men (good for spies or coercion) to muscle-built women and men (good for smashing heads).
12. Day/night cycles. Able to see all 4 seasons. All types of weather: sunny, cloudy, rainy, hail, snow, windy.
13. Easy to use map editor for the modding community.
14. First person perspective. Third person is ok, but coming from a FPS gamer, I really liked how Deus Ex: Human Revolution used the first person shooter style. You just get more into a character in the first person view. But don't be afraid to have mirrors so I can look at my character. You could also allow players to use both.
These are just some thoughts, but it would be nice to see any of them used.
