Legendary Wars for iPad (& iPhone) $1.99 for iPad and $.99 for iPhone is a beautifully well designed game by Liv Games that has humor and best of all fun. The basics of the game are you create an army to fight the monsters that are attacking. The great thing about this game is as you gain gems you can upgrade the stats of each type of defender you have (and there is lots of types). Once maxed out you can then upgrade their armor to become even more powerful.
This game has been compared to Plants Vs. Zombies which I think is very fair and that is good company to be associated with. All in all this game is a must get I have been hooked for days and can not wait to see what else they can bring to the game in an update or sequel!
