As people have gotten more savy with computers, and developers are starting to make it more and more possible to mod their games, it ponders the question: Will developers give you the basics of the game, but provide you the tools to finish it to your liking?
Say we have a new RTS game. Its base is a Space Conquest game where you build structures, build units and conquer planets. You buy it. Now they provide you with the AI and programming, a couple of designs, effects etc., but they don't provide you with the actual game because its up to you to finish it.
It would be like the Editors for Galactic Civilizations: Twilight of Arnor to a degree. You would than assemble it like such:
Make workers units to collect resources by inserting "Gatherer" and "Builder" commandlines, along with a design or one you would make yourself. And you would have it for your game.
Create the type of game by providing victory options "conquer X and Y planets" or "Capture this X ship and bring to Y" commandlines. And so on.
The advantage would be that you're provided the components, but ulitimately its you who finishes the game to your liking. So you could make the game you wanted of the engine that the developers made, and provide a longevity for the game. Developers can also create additonal packs for their base game that add more components for you to work with, but you have to buy them. Also you can't yell at the Developers, for balance or over-powered issues because your the one making it. The only thing they could be accounted for are errors and crashes of the engine itself.
The Disadvantage is that you have to finish it which means work for you to actually run the game at all. The other is that Multi-player would be close to impossible because of the vast differences in the game designs of the same engine.
Some of you will bring-up "Well there are plenty of games that have scenario and editors. Heck there's one you just listed!" True. But that's a FULL game that already has a default way of playing. For example you can play as the Dregin empire and conquer the galaxy. In my idea, there would be no such thing. You wouldn't have a Dregin from the beginning, you would have to build a "Dregin", the galaxy, and insert the victory commandline yourself..
So in a nutshell buying a game in this way would be like getting a Lego or Model set. You're given the parts, but you need to build it yourself.
Personally I think this would be cool. Not sure if it could be mass-marketed because people to like buy things that don't involve much effort (Why we occassionally eat out), but again people buy miniatures, models and the like as a hobby. So would this be Game Modeling?
