i started with torquescript and it DID kinda mess me up later down the road with C++ and whatnot, but basically it was a good brain activity.
i think any language is good in that sense, regardless of which one you do first (as long as it's not a baby language like batch or something, let's not even consider that a language).
logic, inference, creativity, and rationality. qualities that you should have and develop to be good at any programming/scripting/coding/anything.
i think, for me, mostly it was just fun to have something to challenge my brain a bit and have a neat end result. (problem is it's harder to challenge it now and i lack sufficient inspiration to try so i end up not actually doing much anything anymore :c)
this is why i'm confident about setro2 coding, maybe it'll help him develop a bit of logic and whatnot, and he'll be a bit less dumb (sorry, setro, it's the truth but that's fine i guess). granted that he actually tries.
