If you could create a single game

[Amgeo]

I've actually spent a lot of time thinking about this. My game would be a Metroidvania-style 2-D platformer where the player character is armed with only two things; a grappling hook and rocket boots. This may sound redundant until you realize all the options that it gives you. You can fly around with your rocket boots, bashing enemies, set them on fire, etc., or use your comparatively quiet grappling hook to hide in high places, swing along and kick an enemy right in the face, grab stuff and toss it around, all good stuff. But the real kicker is when you use the two in conjunction. Grab an enemy, fly up to the ceiling, then drop him onto his coworker. Slowly lower yourself until you're directly above an enemy, then turn on your boots and fry him! The possibilities are endless!

Dungeon keeper 3 and Evil Genius 2. Then on to some Transport Tycoon 2 or Locomotion 2 (notice these are all sequals).
To finish off I want a deadpool game, with the quality of the recent Batman games. You know, just to break more 4th walls than a demolition crew.

I was just thinking the other day how badly I want another Spider-man game like Spider-man 2. The swinging was just -right- in that one. It hasn't been replicated since.

And a Marvel: Ultimate Alliance 3 on next-gen consoles could be pretty great.

Also, Xylophone Hero.

A massive space sim with a complex trading system, race relations and interaction with the world. Also the fighters would control similarly to games such as the Freespace series and the X-Wing series but the capital ships control like the ships in Star Trek: Bridge Commander.

I've made 2 similar threads about specific types of video games here:

So, yeah, I've got quite a few ideas.

I would make a FF game where you play as the villain . Hopefully a villain as awsome as kefka.

Personally, I'd like to see any game where you could be a villain as incredible as Kefka.

As for your other idea, why not go the Tales series route and just make who the REAL villain is less than obvious.

I'd love a spaceflight simulator (using the term "simulator" loosely) with X3's trade/fight/build/think mechanic set in the Star Wars universe.

Also, get Bethesda and Bioware to join forces in making Jade Empire II - loved the original but it always frustrated me that I couldn't just set off and explore the land Skyrim-style.

This idea's probably getting a little old by now but a Pokemon game where you can go to all the regions.

If I could have anything in the world? An open world first person rpg on the Arcanum licence.

Ah... a girl can dream.

Legacy of Kain game in 2D. The fast pacing of the game Alien Soldier for the Sega Genesis + A plot that revolves around solving most of the questions brought by the nature of some omnicient characters, clarifing the rules of time travel and timelines and solving some problems of characterization and plot holes that Blood Omen 2 left us = My game (i do have to think of what kind of puzles shall be implemented on a 2D game around that series protagonist)

I would create a game where you played as a private detective it had the L.A Noire crime solving, Batman: Arkham Asylum/city stealth and combat, third person shooting and Assassin's Creed free running in an open world present day London.

I don't know what it would be called.
