Perhaps a little Biased...

Game: Tiny Warz

What can i say? i play the game and i love it, so maybe there is some bias in my score. But none the less: I have found this game to be great fun, and most importantly you can play on all levels. You don't have to put real money into the game to do well, you don't have to spend a lot of time on the game. You don't even need a huge internet connection. Also, the game is constantly updating, and i have found any large updates to fit in extremely well with the rest of the game (the Battle Tech strux as an example) When it comes down to it, it's free, give it a look and see what happens. If you are looking for ultra high-tech 3D graphics and what-not this probably isn't for you. But then again neither will most free games. All i did was try it out, and i'm still playing.
