Welcome to Steemit. You sound like you will probably fit in well here. There's a reasonable size gaming community here and a reasonable interest in cryptocurrency (which makes sense given what the site is - but there's a reasonable amount of interest on the investing in other coins, getting more technical side too as opposed to just thinking about steem and that's all).
I know there's some programmers around but I'm not quite sure how big that community is on here. I myself am studying Digital Media Technologies which has been covering some programming like creating websites and C# (We're learning PHP at least this semester that just started but I think there's more as well), but it also focuses on the arty side of IT a bit with courses on graphic design in Photoshop, Illustrator etc and courses on video editing and animation etc (which is quite useful to me as well as I do these things outside of study). It's a fun mix. I mostly made a HTML5 shooter game last semester but a few things didn't quite work and I haven't returned to it after the semester finished yet to work it out, but I intend to because it would be cool if I could get it working and add it to my website (it was made in Notepad ++).
I have to make some kind of project this semester which could be an app to go in Google Play / App Store or a website or any other suitable options really, so that should be interesting.
Nice to meet you. I hope you find Steemit to be a nice place.
