Framework Brainstorm

[unurhoogs]

So we are this company with currently 3 browser based games. We are just 4-5 coders employed and would really like to improve the synergy from our coding.So we are considering making a more generic framework. Currently our games consists of one big mix of html, php, javascript, css & flash (+databases).So basically I would like to have only one forum code, one message system code, payment gateway etc, instead of all the pages we got now thats 'almost' identical and yet so far. What technologies and structure would you guys recommend for making this mess more module based and generic.The sites in question arehttp://trophymanager.comhttp://trophyhockey.orghttp://bigbuckcity.com
