Damn , every time I post the gamestudio community gangs up on me : \ About the bubbles game , yeah it was simple , and yes it didnt push A6 limits , but it wasnt suppossed to , I even downgraded gamestudio to 6.22 to use DX 8 instead of 9 , and the textures are all like 64x64 if i remember correctly , the only thing that did use more memory was the skycubes , which I now wish I woulda used a cheap skybox for instead.

///////////New Paragraph/////////////////

The thing about the model from jigga , if it's meant to be a detailed model to be viwed up close in a fps game , why didnt he mention it on his post , and why didnt he include some close up screenshots ? I was left with the impression that the model was suppossed to be a simple house in a town or something , nothing to fancy , but then here comes the answer to your question , sicne your the only one who really knows how important a model this house will be in the game , your the only one who can really decide how many polys you want to spend in it , it can be under 50 , or over 1000.

///////New Paragraph//////////

But so this wont just be a waste of time , here are some links of some fairly high detail/quality huose models similar to yours which are suppossed to be game-ready , so you can get an idea more or less of how many polys you can spend in 1 house depending on the quality you have in mind.
