"what language/s have you developed in before?" Basic, 6502asm, 68000asm, GFA Basic, VB3-6, BlitzMax, C++ and now AS3. Nothing on a pro level, just lots of fiddling about over the years. AS3 reminds me alot of coding on the Atari ST. I feel like I've gone back in time doing all the copypixel stuff. Reminds me of all the software blit routines I coded back then.
