online games

Im making a strategy game (not in Drupal, only PHP with Javascript, you can see in in here www.iasoftgroup.com/xeno). For the login system I use a simple user login/register module. It doesn't do a lot, just the basic data sanitation, so it ocurrs to me that maybe i can use the Drupal API to make it work for me.

So I wanna know similars experiences and ideas of how this could be done. If it easy to do it?. Are there any problem or pitfall that we should be aware of?

This is as good a time as any. The RPG module is in official Alpha. You can make characters, walk around, and pick up & drop objects now. The rest is window dressing... ;) I've attached a screenshot here.

You can make a character at DrupalRPG.org. If you do, some caveats: [EDIT] set the 'PC' attribute to your user uid on the character creation page [/EDIT]; make sure to set a location to one of the two rooms currently available; when you walk around, the messages don't work entirely. If you take something, make sure you leave things on the floor for other people to take.

There's only a few rooms right now, and a few objects. Things will probably get cluttered very quickly as people make characters and objects, so I'll probably have to do some housecleaning soon.

I just updated the RPG project page with a more current description. To add to the discussion, I'm cross-posting the juicy parts here and at Drupal RPG. (Sorry in advance for the spam if you're subscribed to the three posted groups...)

RPG

The engine itself does little more than provide a core to build a game with. Although it is intended to be for online RPG's, there is no reason the base couldn't be expanded to create other types of games, such as Turn-Based Strategy games, RTS games, or even slidescrollers. The engine is able to do this by providing basic functionality for administrators to create, use, and share 'rulesets'.

Rulesets are definitions of the Types, Attributes, and Actions used to create in-game objects. They may be created in forms available to game administrators, and may also be imported/exported from forms or even files. RPG Object Types follow inheritance rules, and may even include multiple parents, allowing types to share and even override attributes and actions.
