You may play it with an emulator, you will like it, but it's very scary than Silent Hill 2.
I've played a lot of games, and I am offended by this. Silent Hill 2 is branded as a horror game, but it also has one of the best storylines of any game.
GamesRadar lists Silent Hill 2 as the #1 best storyline of all time.
One idea, what about an old fashioned game like "Mario Typing" where you can add your own dictionary?
This game have educational purposes and teach playing xD
I remember playing educational games in elementary school. In particular, the Math Blaster series. I wonder what 'modern' educational games look like, but I definitely believe gaming will make major strides in the educational sector in the near future. The military is already using games - the civilian factor will be soon to follow.
"Blind Game" where you can't see anything, but you hear everything and feel like you are in the scenery. So only put your earphone close your eyes and open your minds.
I'm studying Octophonics to make that game come true...
When I interned at an IT company as a web developer, we had to make sure our sites were compliant with some federal regulations. These regulations stated that our games had to account for people with disabilities. As a game developer, I think it's wise to not limit our audience, at least not if we intend to make any sort of profit from it.
It's a perfectly viable idea, though.
Sid Meier's "Civilization" meets Tower Defense. Everyone begins with primitive (say, stone throwing) towers and as they advance through the game, decide to spend the points they accumulate during gameplay on various Civilization improvements. (Irrigation = More Food, essential for People-Producing towers. Mysticism = Magic-based towers. Imperialism = Phalanx-Producing units that can outright stop the flow of enemies while they fight to the death, etc).
This system allows you to incorporate dozens (perhaps a hundred?) tower variants, so each playthrough of the same set of levels can feel different.
This is interesting, but you have to understand that part of the appeal of Civilizations is the alliance aspect and 'conquering the world'.
You're Ronald McDonald at a kid's birthday party, when suddenly the Burger King bursts in through the living room wall with all other fast food mascots behind him, and he tells you he's gonna kick your ass for making kids eat horse meat - if you don't defeat all other mascots and the King himself; but if you do, you'll become the new "burger king". You also unlock the other characters, new outfits and stages, and a new title screen. But you start out with Ronald in his typical clown outfit and fight each mascot in his own stage; or you can do Adventure Mode, wherein you race across different fast food themed levels before fighting the level's boss (a mascot); so Adventure Mode is just like the other normal mode but with levels. Beating the game with all the mascots unlocks secondary fast food characters like the Hamburgular, who can help out in fights (either automatically, when you press a button, or when your character dies) and unlocks the level editor, so you can create your own stages and levels, than use them in the main modes (in addition to or in substitution for the regular stages and levels) if you want.
I'm certain there are intellectual property rights issues with this.
I like some parts of your ideas, but the scope is a bit ridiculous.
