Here is a link for reference on vanilla games. For new hosts, you may want to create your setup based on a vanilla setup. If you want to add more TPR, then balance the vanilla so that town has a less chance of winning (which will be offset by the TPR). This shouldn't be followed like a bible, but it's a good jumping off point for new hosts of FM.
