Yes I think so . PB is really fast and compares to C++ in the speed stakes as far as I'm led to believe . The ogre graphics are very nice to work with .
I'm still new to programming although......
Am thinking along the lines of GTA not the same but a simplified version with roads and trees and buildings .
This guy on one of his games sold 24000 copies on steam and earned $90,000 . Anyway first things first and that means write a good game . Sounds like a plan . onwards and upwards , I hope .
I'm not saying it'll be as good as GTA5 but I think if done correctly it could be a good game
