This is my second try because I''ve posted this to wrong forum, so now after sugestion of "Avatar God" I''m posting it here: I want to create a game where player is building a model from given parts. For example : you have an inventory in which you have car parts like wheels, doors, bumpers etc. and you need to build full model from this parts. My question is : do you know if someone has written such thing already, so I can see how it is done,before I start coding this? Thanks for any reply

Only half related, but here it goes: Pontifex/Bridge Building Kit is a game from chroniclogic.com where your task is to build and test bridges.
