This game could have been very, very good. It has a very unique, well-presented concept : you get to play as a James Bond villain, complete with the stupid minions, eight-feet tall bodyguards and shark-filled traps. The art and concept teams did a great job, creating very interesting characters and buildings that makes you want to unlock everything and to find out what the game has to offer.
The one problem this game has is its pace, and it's, sadly, a crippling issue. No matter how well optimized your base is, you will spend most of the game waiting endlessly for minions to be recruited, trained and outfitted so you can attempt missions. Those "missions" only require you to have the right number of henchmen, to click on a button and to wait (and hope) until the mission succeeds or fails. That's it. You don't get to do anything else, you don't get to command your soldiers as they attempt to steal a german satellite or whatever you sent them out to do. Clicking "Start mission" and waiting. That's all there is to this game besides base building and it's a little underwhelming.
Then again, it would all work perfectly if you did not have to wait for dozens of minutes for your henchmen to be recruited and trained for missions. The worst part is that you always have to choose between waiting less or playing efficiently : recruiting minions faster costs money, so if you want to use your money carefully (and you will), you need to wait even longer. Same goes for your missions : you need to send henchmen away from your base so they can steal money... which makes your missions' progress even slower, because the henchmen you're using to steal money can't go on missions. There is no way to increase the game's speed either. It's like the developers really wanted the player to choose between waiting for long, unproductive minutes or to use his hard-earned funds to actually keep playing the game. It's not rewarding at all and makes the whole game feel like a grind.
I have played about twenty hours because every once in a while, I tried giving the game another chance, reinstalled it and started another playthrough, only to get tired of it at the same point, after five or six hours, every time. It's just so terribly slow, so full of waiting and almost devoid of actual gameplay besides the base building that is also very, very slow once you spent your initial funds (because earning money in this game is also very slow and difficult). To me, Evil Genius will always be the game that could have been, and that never will be.
