Got no time to make any simple games from scratch. I would rather use an all ready game engine such as Unity if I am planning on making a simple indie game.
Not really interested in JavaScript lol, only C/C++.
I used Lua for some time before when my C/C++ knowledge was low. It was in my my C&C Renegade server. Btw the Lua was a wrapper from C/C++. I guess it was fine, not bad.
