Holla at microsoft.

I am not the biggest fan on microsoft and their game products. But There is something that i like. That thing is a game of theirs. It is called Rise of nations and it is a real time strategy. The thing that really got me going on that games was the reasearchs. To be able to do a research in order to build something you need to have university. In the univeristy you pay for a certain amout of proffesers which produce knowledge. In the univercity you have no more than 7 proffesors to produce you knowledge. You that is not enough for your needs then you build more universities in order to get the amount of knowledge you need faster. There is ratio on how quick you raise the knowledge. The more universities you have the faster the knowledge you need is gather. For exaple in yoi have one university with 7 proffesors you raise 7 times 20 that makes 140 knowledge for a certain amount of time. If you have 2 fully loaded universities that make 14x21 that makes 294 for a certain amount of time.
There are a lot of aspects of the game i really would like to talk about but i will just take a quick note on several of them. There is a city center around which you build your building. You can build only certian amout of buildings. For instance you can build only one university per city center. The city center it self cant be destroyed. If a person attacks you he has to take it over and keep it for a certain amout of time in order to make it his. You can defend it with your works too like a stronghold. There are also wonders when you build them they give you some bonuses. I do not want to spoil you pleasure of playing the game so i think it is time to shut my mouth for now. One last thing the game features very nice campaign to take over the world. Do not hesitate and try it you wont regret it!
