Creating a world system can take almost as long as writing a game. Since Ive spent 9 months on a game that is still no where near completion I don't consider it an option. I'll wait if I have too but I thought P5 was about fixing BSP bugs.
So far I can make the BSP, light and collision etc. I can use it in my game and it's fine for playtesting. If I didn't keep falling through he floor with P4 I would be delirious!!!
It's enough to make you wonder if your on the right planet!!! or
Get it straight! War breaks out and nobody shows up!!!
