So here are the two games I was talking about:
|Screenshot from Minicraft|
|Screenshot of Dwarf Fortress - yes that's how the vanilla game looks like|
And now my idea:
(I did mention that names are not that easy right?)
Gameplay: You control one character in a random generated world which is kinda 3D (don't know how to describe properly but you have an x, y and z axis). You would just need keys to move in the world plus one for interaction with objects, one for your inventory and one for your character screen. You would start with just a few tools but similar to minecraft you can chop wood or mine into mountain to get stone and ores to produce better tools, weapons and armor for yourself. You are not alone in the world with enemy of different strengths will roaming around and attack you if the spot you so you always have to be ready to defend yourself. Of course you always can choose to build yourself a house or any other kind of safeplace because you are able to build walls, floors, doors and all those kind of stuff with the materials you collect. You could go on like this as long as you want while improving yourself and exploring more and more of the world. Up to this point I guess it's pretty much minecraft with a different view but i want to give the player the opportunity to build up city in this game. You would do so by building some sort of special buildings which attract NPC who populate them and do different jobs in your city. An example would be to build a little house with fields nearby which would attract farmer to join you. All in all there would be different profession from guards to smiths and so on and you would need a good mix of them to keep your city running well. All the NPC are controlled by the computer so your task is not really the micro management but more the macro management.
Story: You are a refugee from an evil empire and fled to unknown lands in order to escape some kind of punishment. You can choose to try to survive on your on or as pointed out above you could try to unite other refugees and build up your own city and maybe even an empire to fight the evil empire.
By the way I found an article interviewing Notch the creator of "Minicraft" where he speaks about innovation and ideas (and some other stuff) and I think he would agree with my statements at the beginning of the article. You can read it here. So at least one of the creator of the influencing games would not sue me for realizing this ;)
