Ugh. The A5 templates are what made me start learning C-Script. Seriously, even when I learned how to start using them properly they were just awful...
Player physics are retarded, the enemy AI is as dumb as a brick, the built-in weapons don't handle realistically whatsoever, and it's missing too many features to build a complete game with it.
Also, every game I made had that "cookie-cutter" feel, which I hate.
I've even toyed around with the idea of making a web-comic that pokes fun at the old A5 templates, called "Template Adventures: Starring C-Babe!"
