This flash game popped up on Newgrounds a couple of weeks ago. I was actually one of the people who voted on it before it was officially accepted into Newgrounds, so I got a protect point out of it. What's also cool is that it's the #1 flash on Newgrounds right now.
Mastermind is part real-time strategy, part simulation. You control Mastermind, a character who wants to take over the entire world. You can buy minions, henchmen, businesses and the like. The main goal of the game is to steal knowledge that will make you scientifically powerful enough to take over the entire world.
The game engine is amazing. From a top-down view you gain control of your army and the controls are very responsive. You can also buy equipment and partake is special world events within the game that can help you make a lot of money. You have a ton of choices throughout the game, and you'll expand out quite quickly.
The voice acting is also superb, which is extremely rare for a Flash game. Make sure you listen to the tutorial thoughl as the controls can be confusing. They break it down nicely though, no worries.
