Game Project

I’m planning to work on a game that functions similarly to fire emblem and advanced wars.
I was going to start working on creating it in Flash CS3, when I suddenly had a thought: What if Flash isn’t the best tool for creating this game?
I would like to ask all of you lurkers on kirupa forums that if I were to make a game like this, would Flash be the best tool for it.

Thank you for your help everybodies!
