Well i got the game. I've played three levels so far and here is my first impression review.
Thorium Wars has amazing graphics (especially for being dsiware). The controls are real easy to master (by the way, you can change the controls in "options" menu during a mission). All the vehicles are pretty fun. There are two major cons though (so far). First off, on the levels I played they all had these pesky little anoying flying droids that would just keep coming at you, which can be extremely annoying when you are trying to destroy some "energy core". The droids were never a real threat, but when you find out you died all because some pesky little droid fired this almost nearly harmless shot at you, it can be nerve recking. I also hated how long each mission was. So far, all of my missions have averaged 30 minutes which is pretty long if you ask me. Other than that, its all great (the price could've been a little lower though). At the same time you'd also have to like this kind of game to really get into it, so its not for everyone. Overall 7.75/10

But I'll say no more until the review is up. Don't want to steal my own thunder, after all...
Incredible.
