Yeah I’ve used wine to get a few games working (and steam, steam and the source engine work pretty well) but in general it’s just a faff and ubuntu linux games themselves tend to be rather hit and miss was just after a few recommendations.
As for what I’m interested in doing, just things that help boost productivity (ie. guake) and interesting little things that just make everyday tasks a bit quicker. I’m also a software dev so stuff linked to that would be good too!
Also, I’ve found mint to be really good, I like the layout and it’s pretty fast too.
