Decent Game-Engine for First Person Stealth Game?
I try to practise C++ right now so i thougt coding game. And for that reason i think a FPStealth like Thief Gold would be good starting point. But since i have no real clue what i should focus on if it comes to "details" like the engine im asking this question.
First of all you should practice english, there are a lot of grammar mistakes in your text.
Next you should google for "game engines". I think Source Engine would be a good idea since it uses C++ afaik.
