Hi Rachel, welcome to the Forum (which seems fairly quiet at the moment!)
There are no games templates as such (except for a, to be fair, fairly primitive template in Rev Media for creating adventure games, although you still have to learn scripting).
There are a few games-based stacks around: if you go to RevOnline once you've purchased Rev or using the Demo (one of the buttons under the Rev menu bar, if you don't know) there's a Games category; you might find some stuff there.
You might have seen in this Forum, under the heading Revolution Media and Spotlight, the category called Games (Adventure Game Maker or roll your own)which might point you to finished games stacks.
There's a step-by-step guide to creating a Hangman game stack here:

You might consider Malte Brille's excellent plugin called Animation Engine if you start your own scripting in earnest (scripting can be fun when you get the hang of it!):

Here's a couple of gams made by other Revvers (although you can't get into the coding unfortunately as they are compiled apps):

Buying Revolution to create games is fine but ideally one needs to learn scripting to get any sophistication. Although I think RR is the "bees-knees" you might consider purchasing a program specifically for making games:

is a useful site, the majority for PCs.
If you enjoy graphics but if I understand you correctly, not much into scripting, and you use an Apple Mac, I can highly recommend a Mac game making piece of software called Power Game Factory:

Hope that's all been of some help!
