Samuel Otero is the creator of the Android/Flash game Pokemon Tower Defense released in March 2011. Due to a recent interview with Sam, He stated how he came up with the idea for Pokemon Tower Defense, saying:
"I really like Pokemon and always wanted to make a Pokemon game but was discouraged from finishing them due to various reasons. When I got into the Android Marketplace I noticed a lot of apps that used Nintendo Characters or other characters so I thought why not. The game started originally as a virtual pet simulator. I started planning it out on paper and I realized it was going to be a lot of work for just a pet sim, and at the time I looked at what the most popular paid game was. It was a "tower defense" game so I immediately thought about capturing your enemy and leveling up your towers like Pokémon"
