I've actually thought about that quite a bit, and naturally it incorporates some elements from my favourite games.

You'd have a few planets (7-10). Each area (planet) would be open, but would of course be enclosed to only that planet. And no, the areas wouldn't be planet-sized. Each area would be rather big, but not too big. Think big enough that you could explore for a while, but not so big that you can't explore it all.

Gameplay would be like Ratchet & Clank (Everyone saw that coming, right? ) but focus a bit more on the platforming. Your weapons upgrade, but in this game, other things, like your hoverboots and your boost jump would also be upgraded, so you add a few more RPG elements.

Have some bigger side questlines, and a mainquestline, just like in your normal WRPG, and of course you have the challenge mode.

So basically, what I'd make is an R&C with more exploring and more RPG elemts xD

What an amazing coincidence, my game would be banning gaming forum trolls!

You complete me... ♥♥♥

It would probably be a mmo gta game,with endless posiblities,that would be my dream.

I would like to fund this.  Do you have a kickstarter? lol

OT: Definitely a JRPG!

Something like Uncharted or Grand Theft Auto.

I have two projects in mind, though at the rate I'm learning to use Unreal 4 might as well just die of old age without having finished anything xD

One is a free-roaming on-rails detective story; I've thought deeply on this one, and I have two different versions with two different cast and two different stories altogether, I can't decide for which one to go. On one version, you play as a private eye who stumbles upon a crime and a singular writer called Lucky; they both team up and end up discovering the secrets behind the city they live in. Game would play going from locations, mixing up clues you get in order to bring up results, and some confrontational moments on which you shoot your way out, Time Crisis style. The other version would feature a contracted hitman, a para-medic and a journalist that have to solve three different misteries in three different places on the world that end up connected somehow. Gameplay would remain largely the same.

The other one is a traditional RPG àla japanese style (think of FF IV) featuring three protagonists who design a flying machine that allows them to explore the world past the ocean, since the water in this universe seems to kill everything that ventures in it.

I would make sort of a cinematic video game where the main character is a female with a hijab (I realized I don't know any video game characters with a hijab).

Most probably a schmup or metroidvania.

A WRPG set in space, where you can vastly explore many planets inside a system. The character has a skill tree where he can implant a specific set of skills (a la Mass Effect). I'd include a lot of attractive and relevant skills with balancing limits so players feel inclined to choose different play styles. When he's part of the Elite soldiers, his skill tree will improve with unique skills used to face the more powerful enemies.

The game won't limit itself to humans, but it will also include several alien races, friendly and hostile.

I'd include an extremely deep customization system with an insane amount of detail. The customization won't end only on character and clothing, but it will expand to weapons, space vehicles, ships, living quarters, space stations, outposts, among others. And clothing customization can go from civilian clothes, space exploration suit, stealth outfit and mech customization.

Apart from the main missions, there will be side missions too, varied and engaging; not just a "get me this McGuffin from 10,000,000 miles away and protect yourself from 10 waves of enemies". I'd make missions engaging, dynamic and unexpected.

Also, this game would have a looting system where the player will have a massive universe to explore. With the loot he finds, he'll be able to craft improved versions of weapons, armors and gadgets.

In short, this game would be inspired by Mass Effect, Dead Space, Metroid, Alien: Isolation and Fallout, with a touch of a humorous approach varying from vulgar to smart.

The main character is an arrogant but lovable douche who never seems to take things seriously. He's part of the galactic army and he dreams being part of the elite group of soldiers. He later finds out that galactic soldier life, while not being what he imagined, at least made him more relevant than when he was a bottom-feeder. As time went by and as he experienced many brutal things, his mentality changed and he was now one of the elite. An alien invasion occurs and things get more insane. His mentality takes a turn for the worse and he's then struck by a dilemma: join the aliens and take over the outgunned and outmanned human race in exchange for mental peace, or just kick some alien ass in an epic fight.

Do note this was just improvised.
